net/mlx5: Rate limit errors in command interface
Any error status returned by FW will trigger a print similar to the
following error message in the dmesg.
[ 55.884355] mlx5_core 0000:00:04.0: mlx5_cmd_check:712:(pid 555):
ALLOC_UAR(0x802) op_mod(0x0) failed, status limits exceeded(0x8),
syndrome (0x0)
Those prints are extremely valuable to diagnose issues with running system
and it is important to keep them. However, not-so-careful user can trigger
endless number of such prints by depleting HW resources and will spam
dmesg.
Rate limiting of such messages solves this issue.
