net/mlx5e: Fix update of hash function/key via ethtool
Modifying TIR hash should change selected fields bitmask in addition to the function and key. Formerly, Only on ethool mlx5e_set_rxfh "ethtoo -X" we would not set this field resulting in zeroing of its value, which means no packet fields are used for RX RSS hash calculation thus causing all traffic to arrive in RQ[0]. On driver load out of the box we don't have this issue, since the TIR hash is fully created from scratch. Tested: ethtool -X ethX hkey <new key> ethtool -X ethX hfunc <new func> ethtool -X ethX equal <new indirection table> All cases are verified with TCP Multi-Stream traffic over IPv4 & IPv6.
