net/mlx5e: Support XDP target xmit with dummy program
Save per-channel resources in default, in device and host memory.
As no better API exist, make the XDP-redirect-target SQ available by
loading a dummy XDP program.
This improves the latency of interface up/down operations when feature
is disabled.
Perf numbers:
NIC: Connect-X7.
Setup: 248 channels, default mtu and rx/tx ring sizes.
Interface up + down:
Before: 2.246 secs
After: 1.798 secs (-0.448 sec)
Saves ~1.8 msec per channel.
