net/mlx5e: Support offloading TC NIC hairpin flows
We refer to TC NIC rule that involves forwarding as "hairpin".
All hairpin rules from the current NIC device (called "func" in
the code) to a given NIC device ("peer") are steered into the
same hairpin RQ/SQ pair.
The hairpin pair is set on demand and removed when there are no
TC rules that need it.
Here's a TC rule that matches on icmp, does header re-write of the
dst mac and hairpin from RX/enp1s2f1 to TX/enp1s2f2 (enp1s2f1/2 are
two mlx5 devices):
tc filter add dev enp1s2f1 protocol ip parent ffff: prio 2
flower skip_sw ip_proto icmp
action pedit ex munge eth dst set 10:22:33:44:55:66 pipe
action mirred egress redirect dev enp1s2f2
