[ Upstream commit 34e59836565e36fade1464e054a3551c1a0364be ]
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
