This is a note to let you know that I've just added the patch titled bnxt_en: reject indirect blk offload when hw-tc-offload is off to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: bnxt_en-reject-indirect-blk-offload-when-hw-tc-offlo.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c44fc2b065a00ced4f7842b149185b4d1d912f62 Author: Sriharsha Basavapatna <sriharsha.basavapatna@xxxxxxxxxxxx> Date: Mon Nov 15 02:38:01 2021 -0500 bnxt_en: reject indirect blk offload when hw-tc-offload is off [ Upstream commit b0757491a118ae5727cf9f1c3a11544397d46596 ] The driver does not check if hw-tc-offload is enabled for the device before offloading a flow in the context of indirect block callback. Fix this by checking NETIF_F_HW_TC in the features flag and rejecting the offload request. This will avoid unnecessary dmesg error logs when hw-tc-offload is disabled, such as these: bnxt_en 0000:19:00.1 eno2np1: dev(ifindex=294) not on same switch bnxt_en 0000:19:00.1 eno2np1: Error: bnxt_tc_add_flow: cookie=0xffff8dace1c88000 error=-22 bnxt_en 0000:19:00.0 eno1np0: dev(ifindex=294) not on same switch bnxt_en 0000:19:00.0 eno1np0: Error: bnxt_tc_add_flow: cookie=0xffff8dace1c88000 error=-22 Reported-by: Marcelo Ricardo Leitner <mleitner@xxxxxxxxxx> Fixes: 627c89d00fb9 ("bnxt_en: flow_offload: offload tunnel decap rules via indirect callbacks") Signed-off-by: Sriharsha Basavapatna <sriharsha.basavapatna@xxxxxxxxxxxx> Signed-off-by: Michael Chan <michael.chan@xxxxxxxxxxxx> Signed-off-by: David S.
