Hello,

after the latest mellanox update the mlx4 driver fails to probe a VF:
[ 88.909562] mlx4_core 0000:00:00.0: mlx4_allocate_default_counters: failed to allocate default counter port 1 err -22
[ 88.909564] mlx4_core 0000:00:00.0: Failed to allocate default counters, aborting
[ 88.961735] mlx4_core: probe of 0000:00:00.0 failed with error -22

PFs still work. See below for more dmesg output - I also added a line of
debug output...maybe this helps.

Regards,
Sebastian
