ethtool expects ETHTOOL_GRXCLSRLALL to set ethtool_rxnfc->data with the
total number of entries in the rx classifier table. Surprisingly, mlx4
is missing this part (in principle ethtool could still move forward and
try the insert).
Tested: compiled and run command:
phh13:~# ethtool -N eth1 flow-type udp4 queue 4
Added rule with ID 255
