When writing the driver's struct ice_tlan_ctx structure, do not write the 8-bit element int_q_state with the associated internal-to-hardware field which is 122-bits, otherwise the helper function ice_write_byte() will use undefined behavior when setting the mask used for that write. This should not cause any functional change and will avoid use of undefined behavior. Also, update a comment to highlight this structure element is not written. Signed-off-by:

In current implementation number of XDP Tx queues is the same as the number of transmit queues, which is not always true. This patch changes this number to match the number of receive queues. XDP programs are running on Rx rings, so what we actually need to provide is the XDP Tx ring per each Rx ring so that the whole XDP ecosystem is functional, e.g. if the result of XDP prog is XDP_TX then you have the need to access the XDP Tx ring.

A race condition between FW and SW can occur between admin queue setup and the first command sent. A link event may occur and FW attempts to notify a non-existent queue. FW will set the critical error bit and disable the queue. When this happens retry queue setup. Signed-off-by:

Currently, if the PVID is set in the VLAN handling section of the VSI context the driver still allows VLAN stripping to be enabled/disabled. VLAN stripping should only be modifiable when the PVID is not set. Fix this by preventing VLAN stripping modification when PVID is set. Signed-off-by:

Currently we are only including illegal_bytes and rx_crc_errors in the PF netdev's rx_error counter. There are many more causes of Rx errors that the device supports and reports via Ethtool. Accumulate all Rx errors in the PF netdev's rx_error counter. Signed-off-by:

The manage MAC write command was implemented in an overly complex way that actually didn't work, as it wasn't symmetric to the manage MAC read command, and was feeding bytes out of order to the firmware. Fix the implementation by just using a simple array to represent the MAC address when it is being written via firmware command. Signed-off-by:

Remove is_zero_ether_add() check when setting the VF default LAN address. This check assumed that the address had been delete and zeroed before calling ice_vc_add_mac_addr(). Now the default LAN address will be set to the last unicast MAC address added by the VF. The default LAN address is reported by the PF via ndo_get_vf_config. Signed-off-by:

Fix the remaining signed vs unsigned issues, which appear when compiling with -Werror=sign-compare. Many of these are because there is an external interface that is passing an int to us (which we can't change) but that we (rightfully) store and compare against as an unsigned in our data structures.

This patch adds a field to the tls rx offload context which enables drivers to force a send_resync call. This field can be used by drivers to request a resync at the next possible tls record. It is beneficial for hardware that provides the resync sequence number asynchronously. In such cases, the packet that triggered the resync does not contain the information required for a resync. Instead, the driver requests resync for all the following TLS record until the asynchronous notification with the resync request TCP sequence arrives. A following series for mlx5e ConnectX-6DX TLS RX offload support will use this mechanism. Signed-off-by:

Cong Wang says: ==================== net_sched: reduce the number of qdisc resets This patchset aims to reduce the number of qdisc resets during qdisc tear down. Patch 1~3 are preparation for their following patches, especially patch 2 and patch 3 add a few tracepoints so that we can observe the whole lifetime of qdisc's. Patch 4 and patch 5 are the ones do the actual work. Please find more details in each patch description. Vaclav Zindulka tested this patchset and his large ruleset with over 13k qdiscs defined got from 22s to 520ms. ==================== Signed-off-by: -

Resetting old qdisc on dev_queue->qdisc_sleeping in dev_qdisc_reset() is redundant, because this qdisc, even if not same with dev_queue->qdisc, is reset via qdisc_put() right after calling dev_graft_qdisc() when hitting refcnt 0. This is very easy to observe with qdisc_reset() tracepoint and stack traces. Reported-by:

Except for sch_mq and sch_mqprio, each dev queue points to the same root qdisc, so when we reset the dev queues with netdev_for_each_tx_queue() we end up resetting the same instance of the root qdisc for multiple times. Avoid this by checking the __QDISC_STATE_DEACTIVATED bit in each iteration, so for sch_mq/sch_mqprio, we still reset all of them like before, for the rest, we only reset it once. Reported-by:

Move this code to one helper, to make tcp_v4_err() more readable and to eventually expand RFC 6069 to IPv6 in the future. Also perform sock_owned_by_user() check a bit sooner. Signed-off-by:

This patch adds support for offloading timestamping operations not only to the Ocelot switch (as already supported) but to compatible PHYs. When both the PHY and the Ocelot switch support timestamping operations, the PHY implementation is chosen as the timestamp will happen closer to the medium. Signed-off-by:

The ocelot core library is written with the idea in mind that the VLAN table is populated by the bridge. Otherwise, not even a sane default pvid is provided: in standalone mode, the default pvid is 0, and the core expects the bridge layer to change it to 1. So without this patch, the VLAN table is completely empty at the end of the commands below, and traffic is broken as a result: ip link add dev br0 type bridge vlan_filtering 0 && ip link set dev br0 up for eth in $(ls /sys/bus/pci/devices/0000\:00\:00.5/net/); do ip link set dev $eth master br0 ip link set dev $eth up done ip link set dev br0 type bridge vlan_filtering 1 Signed-off-by:

Therefore update the MRP netlink interface such that each existing attribute to be a nested attribute which contains the fields of the binary structures.
