When implementing pf1-proxy over MLX5-bound VF on PF1 (i.e. setting
sriov_numvfsto1for PF1), maximum throughput on PF0 goes from 24.7Gbps to 12.5Gbps if there is also any VM-VM traffic. Such traffic is also 0.8Gbps.By removing Rx RSS, PF0 throughput is back to maximum and VM-VM if done in parallel is up to 4Gbps.
Part of #606
I have not made this part of the pf1-proxy PR since this change would be easy to miss and I think it should be tracked separately.
