The code for csum_block_add was doing a funky byteswap to swap the even and odd bytes of the checksum if the offset was odd. Instead of doing this we can save ourselves some trouble and just shift by 8 as this should have the same effect in terms of the final checksum value and only requires one instruction. In addition we can update csum_block_sub to just use csum_block_add with a inverse value for csum2. This way we follow the same code path as csum_block_add without having to duplicate it.

This patch updates the GRO handlers for GRE, VXLAN, GENEVE, and FOU so that we do not clear the flush bit until after we have called the next level GRO handler. Previously this was being cleared before parsing through the list of frames, however this resulted in several paths where either the bit needed to be reset but wasn't as in the case of FOU, or cases where it was being set as in GENEVE. By just deferring the clearing of the bit until after the next level protocol has been parsed we can avoid any unnecessary bit twiddling and avoid bugs.

Driver interaction with the managemnt firmware is done via mailbox commands which the management firmware periodically sample, as well as placing of additional data in set places in the shared memory. Each PF has a single designated mailbox address, and all flows that require messaging to the management should use it. This patch does 2 things: 1. It re-defines the critical section surrounding the mailbox sending - that section should include the setting of the shared memory as well as the sending of the command [otherwise a race might send a command with the data of a different command]. 2. It moves the locking scheme from using mutices into using spinlocks. This lays the groundwork for sending MFW commands from non-sleepable contexts.

When device is configured for Multi-function mode, some older management firmware might incorrectly notify interfaces of link changes while they haven't requested the physical link configuration to be set. This can create bizzare race conditions where unloading interfaces are getting notified that the link is up. Let the driver compensate - store the logical requested state of the link and don't propagate notifications after protocol driver explicitly requires the link to be unset.

This fixes a regression in the bridge ageing time caused by: commit c62987bb ("bridge: push bridge setting ageing_time down to switchdev") There are users of Linux bridge which use the feature that if ageing time is set to 0 it causes entries to never expire.

In rocker, ageing time is a per-port attribute, so the next time the FDB cleanup timer fires should be set according to the lowest ageing time.

Commit c62987bb ("bridge: push bridge setting ageing_time down to switchdev") added a check for minimum and maximum ageing time, but this breaks existing behaviour where one can set ageing time to 0 for a non-learning bridge.

Amir Vadai says: ==================== cls_flower hardware offload support Please see changes from V2 at the bottom. This patchset introduces cls_flower hardware offload support over ConnectX-4 driver, more hardware vendors are welcome to use it too. This patchset is based on John's infrastructure for tc offloading [2] to add hardware offload support to the flower filter. It also extends the support to an additional tc action - skbedit mark operation. NIC driver that was used is ConnectX-4. Feature is off by default and could be turned on using ethtool. Some commands to use this code: export TC=../iproute2/tc/tc export ETH=ens9 ethtool -K ens9 hw-tc-offload on $TC qdisc add dev $ETH ingress $TC filter add dev $ETH protocol ip prio 20 parent ffff: \ flower ip_proto 1 \ dst_mac 7c:fe:90:69:81:62 \ src_mac 7c:fe:90:69:81:56 \ dst_ip 11.11.11.11 \ src_ip 11.11.11.12 \ indev $ETH \ action drop $TC filter add dev $ETH protocol ip prio 30 parent ffff: \ flower ip_proto 6 \ indev $ETH \ action skbedit mark 0x1234 $TC filter add dev $ETH protocol ip prio 10 parent ffff: \ handle 0x1234 fw action pass The code was tested and applied on top of commit 3ebeac1d ("Merge branch 'cxgb4-next'") Changes from V2: - patch 1/10 ("net/flower: Introduce hardware offload support") - Remove unused variable [Dave] - Don't fail command when HW can't offload filter [John] - patch 3/10 ("net/sched: Macro instead of CONFIG_NET_CLS_ACT ifdef") - Mention in changelog that struct tc_action is now exposed out of the ifdef. - patch 4/10 ("net/act_skbedit: Utility functions for mark action") - Document clearly that is_tcf_skbedit_mark() is returning true if and only if the only action is mark [Dave] - patch 8/10 ("net/mlx5e: Introduce tc offload support") - make mlx5e_tc_add_flow() static Changes from V1: - patch 3/10 ("net/sched: Macro instead of CONFIG_NET_CLS_ACT ifdef") - fixed return value of tc_no_actions Changes from V0: - Use tc_no_actions and tc_for_each_action instead of ifdef CONFIG_NET_CLS_ACT - Replace ENOTSUPP (and some EINVAL) with EOPNOTSUPP - Name the flower command enum - fl_hw_destroy_filter() to return void - nobody uses the return value - mlx5e_tc_init() and mlx5e_tc_cleanup() to be called from the right places. - When adding HW rule fails - fail the command - Rules are added to be processed both by HW and SW unless SKIP_HW is given - Adding patch 6/10 ("net/mlx5e: Relax ndo_setup_tc handle restriction") Main changes from the RFC [1]: - API - Using ndo_setup_tc() instead of switchdev - act_skbedit, act_gact - Actions are not serialized to NIC driver, instead using access functions. - cls_flower - prevent double classification by software by not adding successfuly offloaded filters to the hashtable - Fixed some bugs in original RFC with rule delete - mlx5 - Adding flow table to kernel namespace instead of a new namespace - s/offload/tc/ in many places - no need for a special kconfig since switchdev is not used ==================== Signed-off-by: NDavid S.

Add ethernet support for MediaTek SoCs from the MT7623 family. These have dual GMAC. Depending on the exact version, there might be a built-in Gigabit switch (MT7530). The core does not have the typical DMA ring setup. Instead there is a linked list that we add descriptors to. There is only one linked list that both MACs use together. There is a special field inside the TX descriptors called the VQID. This allows us to assign packets to different internal queues. By using a separate id for each MAC we are able to get deterministic results for BQL. Additionally we need to provide the core with a block of scratch memory that is the same size as the RX ring and data buffer. This is really needed to make the HW datapath work. Although the driver does not support this yet, we still need to assign the memory and tell the core about it for RX to work.
