Tony Nguyen says: ==================== ice: switchdev bridge offload Wojciech Drewek says: Linux bridge provides ability to learn MAC addresses and vlans detected on bridge's ports. As a result of this, FDB (forward data base) entries are created and they can be offloaded to the HW. By adding VF's port representors to the bridge together with the uplink netdev, we can learn VF's and link partner's MAC addresses. This is achieved by slow/exception-path, where packets that do not match any filters (FDB entries in this case) are send to the bridge ports. Driver keeps track of the netdevs added to the bridge by listening for NETDEV_CHANGEUPPER event. We distinguish two types of bridge ports: uplink port and VF's representor port. Linux bridge always learns src MAC of the packet on rx path. With the current slow-path implementation, it means that we will learn VF's MAC on port repr (when the VF transmits the packet) and link partner's MAC on uplink (when we receive it on uplink from LAN). The driver is notified about learning of the MAC/VLAN by SWITCHDEV_FDB_{ADD|DEL}_TO_DEVICE events. This is followed by creation of the HW filter. The direction of the filter is based on port type (uplink or VF repr). In case of the uplink, rule forwards the packets to the LAN (matching on link partner's MAC). When the notification is received on VF repr then the rule forwards the packets to the associated VF (matching on VF's MAC). This approach would not work on its own however. This is because if one of the directions is offloaded, then the bridge would not be able to learn the other one. If the egress rule is added (learned on uplink) then the response from the VF will be sent directly to the LAN. The packet will not got through slow-path, it would not be seen on VF's port repr. Because of that, the bridge would not learn VF's MAC. This is solved by introducing guard rule. It prevents forward rule from working until the opposite direction is offloaded. Aging is not fully supported yet, aging time is static for now. The follow up submissions will introduce counters that will allow us to keep track if the rule is actually being used or not. A few fixes/changes are needed for this feature to work with ice driver. These are introduced in first 5 patches.

The IEEE1588 Standard specifies that the timestamps of Packets must be captured when the PTP message timestamp point (leading edge of first octet after the start of frame delimiter) crosses the boundary between the node and the network. As the MAC latches the timestamp at an internal point, the captured timestamp must be corrected for the additional path latency, as described in the publicly available datasheet [1]. This patch only corrects for the MAC-Internal delay, which can be read out from the MAC_Ingress_Timestamp_Latency register, since the Phy framework currently does not support querying the Phy ingress and egress latency. The Closs Domain Crossing Circuits errors as indicated in [1] are already being accounted in the stmmac_get_tx_hwtstamp() function and are not corrected here. As the Latency varies for different link speeds and MII modes of operation, the correction value needs to be updated on each link state change. As the delay also causes a phase shift in the timestamp counter compared to the rest of the network, this correction will also reduce phase error when generating PPS outputs from the timestamp counter.

The last s390 machine that supported FDDI was z900 ('7th generation', released in 2000). The oldest machine generation currently supported by the Linux kernel is MARCH_Z10 (released 2008). If there is still a usecase for connecting a Linux on s390 instance to a LAN Channel Station (LCS), it can only do so via Ethernet. Randy Dunlap[1] found that LCS over FDDI has never worked, when FDDI was compiled as module. Instead of fixing that, remove the FDDI option from the lcs driver. While at it, make the CONFIG_LCS description a bit more helpful.

Russell King says: ==================== Remove legacy phylink behaviour This series removes the - as far as I can tell - unreachable code in mtk_eth_soc that relies upon legacy phylink behaviour, and then removes the support in phylink for this legacy behaviour. Patch 1 removes the clocking configuration from mtk_eth_soc for non- TRGMII, non-serdes based interface modes, and disables those interface modes prior to phylink configuration. Patch 2 removes the mac_pcs_get_state() method from mtk_eth_soc which I believe is also not used - mtk_eth_soc appears not to be used with SFPs (which would use a kind of in-band mode) nor does any DT appear to specify in-band mode for any non-serdes based interface mode. With both of those dealt with, the kernel is now free of any driver relying on the phylink legacy mode. Therefore, patch 3 removes support for this. Finally, with the advent of a new driver being submitted today that makes use of state->speed in the mac_config() path, patch 4 ensures that any phylink_link_state member that should not be used in mac_config is either cleared or set to an invalid value. ==================== Link: https://lore.kernel.org/r/ZLw8DoRskRXLQK37@shell.armlinux.org.ukSigned-off-by:

Removal of this, along with the previous patch to remove the incorrect clocking configuration, means that the driver becomes non-legacy, so we can remove the "legacy_pre_march2020" status from this driver.

MT7623 GMAC0 attempts to configure the system clocking according to the required speed in the .mac_config callback for non-SGMII, non-baseX and non-TRGMII modes. state->speed setting has never been reliable in the .mac_config callback - there are cases where this is not the link speed, particularly via ethtool paths, so this has always been unreliable (as detailed in phylink's documentation.) There is the additional issue that mtk_gmac0_rgmii_adjust() will only be called if state->interface changes, which means it only configures the system clocking on the very first .mac_config call, which will be made when the network device is first brought up before any link is established. Essentially, this code is incredibly buggy, and probably never worked. Moreover, checking the in-kernel DT files, it seems no platform makes use of this code path. Therefore, let's remove it, and disable interface modes for port 0 that are not SGMII, 1000base-X, 2500base-X or TRGMII on the MT7623. Reviewed-by:

The MPTCP code uses the assumption that the tcp_win_from_space() helper does not use any TCP-specific field, and thus works correctly operating on an MPTCP socket. The commit dfa2f048 ("tcp: get rid of sysctl_tcp_adv_win_scale") broke such assumption, and as a consequence most MPTCP connections stall on zero-window event due to auto-tuning changing the rcv buffer size quite randomly. Address the issue syncing again the MPTCP auto-tuning code with the TCP one. To achieve that, factor out the windows size logic in socket independent helpers, and reuse them in mptcp_rcv_space_adjust(). The MPTCP level scaling_ratio is selected as the minimum one from the all the subflows, as a worst-case estimate. Fixes: dfa2f048 ("tcp: get rid of sysctl_tcp_adv_win_scale") Signed-off-by:

Replace kstrtoint() by kstrtobool() in the sysfs _store() functions. This improves the user usability and simplify the code. With this fix, it is now possible to use [YyNn] to set and unset a feature. Old behaviour is still unchanged. kstrtobool() is also safer and doesn't need the extra validation that is required when converting a string to bool (end field in the struct), which makes the code simpler.

Port VLAN in this case means push and pop VLAN action on specific vid. There are a few limitation in hardware: - push and pop can't be used separately - if port VLAN is used there can't be any trunk VLANs, because pop action is done on all traffic received by VSI in port VLAN mode - port VLAN mode on uplink port isn't supported Reflect these limitations in code using dev_info to inform the user about unsupported configuration. In bridge mode there is a need to configure port vlan without resetting VFs. To do that implement ice_port_vlan_on/off() functions. They are only configuring correct vlan_ops to allow setting port vlan. We also need to clear port vlan without resetting the VF which is not supported right now. Change it by implementing clear_port_vlan ops. As previous VLAN configuration isn't always the same, store current config while creating port vlan and restore it in clear function. Configuration steps: - configure switchdev with bridge - #bridge vlan add dev eth0 vid 120 pvid untagged - #bridge vlan add dev eth1 vid 120 pvid untagged - ping from VF0 to VF1 Reviewed-by:

Introduce new "guard" rule upon FDB entry creation. It matches on src_mac, has valid bit unset, allow_pass_l2 set and has a nop action. Previously introduced "forward" rule matches on dst_mac, has valid bit set, need_pass_l2 set and has a forward action. With these rules, a packet will be offloaded only if FDB exists in both directions (RX and TX). Let's assume link partner sends a packet to VF1: src_mac = LP_MAC, dst_mac = is VF1_MAC. Bridge adds FDB, two rules are created: 1. Guard rule matching on src_mac == LP_MAC 2. Forward rule matching on dst_mac == LP_MAC Now VF1 responds with src_mac = VF1_MAC, dst_mac = LP_MAC. Before this change, only one rule with dst_mac == LP_MAC would have existed, and the packet would have been offloaded, meaning the bridge wouldn't add FDB in the opposite direction. Now, the forward rule matches (dst_mac == LP_MAC), but it has need_pass_l2 set an there is no guard rule with src_mac == VF1_MAC, so the packet goes through slow-path and the bridge adds FDB. Two rules are created: 1. Guard rule matching on src_mac == VF1_MAC 2. Forward rule matching on dst_mac == VF1_MAC Further packets in both directions will be offloaded. The same example is true in opposite direction (i.e. VF1 is the first to send a packet out). Reviewed-by:

Listen for SWITCHDEV_FDB_{ADD|DEL}_TO_DEVICE events while in switchdev mode. Accept these events on both uplink and VF PR ports. Add HW rules in newly created workqueue. FDB entries are stored in rhashtable for lookup when removing the entry and in the list for cleanup purpose. Direction of the HW rule depends on the type of the ports on which the FDB event was received: ICE_ESWITCH_BR_UPLINK_PORT: TX rule that forwards the packet to the LAN (egress). ICE_ESWITCH_BR_VF_REPR_PORT: RX rule that forwards the packet to the VF associated with the port representor. In both cases the rule matches on the dst mac address. All the FDB entries are stored in the bridge structure. When the port is removed all the FDB entries associated with this port are removed as well. This is achieved thanks to the reference to the port that FDB entry holds. In the fwd rule we use only one lookup type (MAC address) but lkups_cnt variable is already introduced because we will have more lookups in the subsequent patches. Signed-off-by: -

With this patch, ice driver is able to track if the port representors or uplink port were added to the linux bridge in switchdev mode. Listen for NETDEV_CHANGEUPPER events in order to detect this. ice_esw_br data structure reflects the linux bridge and stores all the ports of the bridge (ice_esw_br_port) in xarray, it's created when the first port is added to the bridge and freed once the last port is removed. Note that only one bridge is supported per eswitch. Bridge port (ice_esw_br_port) can be either a VF port representor port or uplink port (ice_esw_br_port_type). In both cases bridge port holds a reference to the VSI, VF's VSI in case of the PR and uplink VSI in case of the uplink. VSI's index is used as an index to the xarray in which ports are stored. Add a check which prevents configuring switchdev mode if uplink is already added to any bridge. This is needed because we need to listen for NETDEV_CHANGEUPPER events to record if the uplink was added to the bridge. Netdevice notifier is registered after eswitch mode is changed to switchdev.

In switchdev mode uplink VSI is supposed to receive all packets that were not matched by existing filters. If ICE_AQ_VSI_SW_FLAG_LOCAL_LB bit is unset and we have a filter associated with uplink VSI which matches on dst mac equal to MAC1, then packets with src mac equal to MAC1 will be pruned from reaching uplink VSI.
