net/mlx5e: Unoffload post act rule when handling FIB events
If having the following tc rule on stack device: filter parent ffff: protocol ip pref 3 flower chain 1 filter parent ffff: protocol ip pref 3 flower chain 1 handle 0x1 dst_mac 24:25:d0:e1:00:00 src_mac 02:25:d0:25:01:02 eth_type ipv4 ct_state +trk+new in_hw in_hw_count 1 action order 1: ct commit zone 0 pipe index 2 ref 1 bind 1 installed 3807 sec used 3779 sec firstused 3800 sec Action statistics: Sent 120 bytes 2 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 used_hw_stats delayed action order 2: tunnel_key set src_ip 192.168.1.25 dst_ip 192.168.1.26 key_id 4 dst_port 4789 csum pipe index 3 ref 1 bind 1 installed 3807 sec used 3779 sec firstused 3800 sec Action statistics: Sent 120 bytes 2 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 used_hw_stats delayed action order 3: mirred (Egress Redirect to device vxlan1) stolen index 9 ref 1 bind 1 installed 3807 sec used 3779 sec firstused 3800 sec Action statistics: Sent 120 bytes 2 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 used_hw_stats delayed When handling FIB events, the rule in post act will not be deleted. And because the post act rule has packet reformat and modify header actions, also will hit the following syndromes: mlx5_core 0000:08:00.0: mlx5_cmd_out_err:829:(pid 11613): DEALLOC_MODIFY_HEADER_CONTEXT(0x941) op_mod(0x0) failed, status bad resource state(0x9), syndrome (0x1ab444), err(-22) mlx5_core 0000:08:00.0: mlx5_cmd_out_err:829:(pid 11613): DEALLOC_PACKET_REFORMAT_CONTEXT(0x93e) op_mod(0x0) failed, status bad resource state(0x9), syndrome (0x179e84), err(-22) Fix it by unoffloading post act rule when handling FIB events.
