This reworks current implementation of MSG_PEEK logic: 1) Replaces 'skb_queue_walk_safe()' with 'skb_queue_walk()'. There is no need in the first one, as there are no removes of skb in loop. 2) Removes nested while loop - MSG_PEEK logic could be implemented without it: just iterate over skbs without removing it and copy data from each until destination buffer is not full.

Daniel Golle says: ==================== net: ethernet: mtk_eth_soc: add basic support for MT7988 SoC The MediaTek MT7988 SoC introduces a new version (3) of the NETSYS block and comes with three instead of two MACs. The first MAC can be internally connected to a built-in Gigabit Ethernet switch with four 1000M/100M/10M twisted pair user ports. The second MAC can be internally connected to a built-in 2500Base-T Ethernet PHY. There are two SerDes units which can be operated in USXGMII, 10GBase-(K)R, 5GBase-R, 2500Base-X, 1000Base-X or SGMII interface mode. This series adds initial support for NETSYS v3 and the first MAC of the MT7988 SoC connecting the built-in DSA switch. The switch is supported since commit 110c18bf ("net: dsa: mt7530: introduce driver for MT7988 built-in switch"). Basic support for the 1000M/100M/10M built-in PHYs connected to the switch ports is present since commit ("98c485ea net: phy: add driver for MediaTek SoC built-in GE PHYs"). ==================== Link: https://lore.kernel.org/r/cover.1690246066.git.daniel@makrotopia.orgSigned-off-by:

Introduce DT bindings for the MT7988 SoC to mediatek,net.yaml. The MT7988 SoC got 3 Ethernet MACs operating at a maximum of 10 Gigabit/sec supported by 2 packet processor engines for offloading tasks. The first MAC is hard-wired to a built-in switch which exposes four 1000Base-T PHYs as user ports. It also comes with built-in 2500Base-T PHY which can be used with the 2nd GMAC. The 2nd and 3rd GMAC can be connected to external PHYs or provide SFP(+) cages attached via SGMII, 1000Base-X, 2500Base-X, USXGMII, 5GBase-KR or 10GBase-KR. Signed-off-by:

MCAM register reports the device supported management features. Querying this register exposes if features are supported with the current firmware version in the current ASIC. Then, the driver can separate between different implementations dynamically. MCAM register supports querying whether the MCIA register supports 128 bytes payloads or only 48 bytes. Add support for the register as preparation for allowing larger MCIA transactions. Note that the access to the bits in the field 'mng_feature_cap_mask' is not same to other mask fields in other registers. In most of the cases bit #0 is the first one in the last dword, in MCAM register, bits #0-#31 are in the first dword and so on. Declare the mask field using bits arrays per dword to simplify the access. Signed-off-by:

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:

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:
