net/mlx5e: E-switch, Add steering drop counters
Add flow counters to count packets dropped due to drop rules configured in eswitch egress and ingress ACLs. These counters will count VFs violations and incoming traffic drops. Will be presented on hypervisor via standard 'ip -s link show' command. Example: "ip -s link show dev enp5s0f0" 6: enp5s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 24:8a:07:a5:28:f0 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 0 0 0 0 0 2 TX: bytes packets errors dropped carrier collsns 1406 17 0 0 0 0 vf 0 MAC 00:00:ca:fe:ca:fe, vlan 5, spoof checking off, link-state auto, trust off, query_rss off RX: bytes packets mcast bcast dropped 1666 29 14 32 0 TX: bytes packets dropped 2880 44 2412 Signed-off-by: Eugenia Emantayev <eugenia@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
