Hi MattJH, i'm currently checking on your 2 questions related to VMQ and RSS. For the mean time, would like to clarify if i captured your issue and setup correctly.
Issue:
Packet loss, high latency on VMs such as 5-6 lost pings request during live migration
Setup:
3 I350-T4 installed on 1 system and configured as one of the Hyper-V. 2 out of 3 I350-T4 configured as Native Win2k12 Teaming (Switch Independent/Dynamic distribution). Total of 4 ports in 1 team. 2 ports belongs to I350-T4 #1 and 2 ports belongs to I350-T4 #2
With VMQ enabled and processor core allocations. Remaining ports from I350-T4 1 and 2 were configured for ISCSI MPIO to access SAN with RSS enabled.
Troubleshooting done:
Turned off VMQ
