Can you please send your "lspci | grep nox" listing? also what
Firmware version you have there? e.g when you probe the PF with
mlx4_core debug_level=1 can you sens us the lines that follow the PF
probe, e.g as here + dump of all caps as you did for the VF

952.367911] mlx4_core: Mellanox ConnectX core driver v2.2-1 (Feb, 2014)
[ 952.374606] mlx4_core: Initializing 0000:06:00.0
[ 953.384332] mlx4_core 0000:06:00.0: FW version 2.34.5000 (cmd intf
rev 3), max commands 16
[...]

Also send us the output of "dmesg | grep -i counter" after such verbose load.

thanks,

Or.
