[ 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
