I have to practically identical systems, same hypervisor on each (Centos 7.x). ?In one, I have a 57800 card which works fine with DPDK with SRIOV. ?In the other, I have a 57810 card which doesn't work with SRIOV.
For the 57810 I have tracked this down to the status block in the VF failing to be updated. ?The linux driver works fine but it appears to use a slightly different scheme -- writing some sort of fastpath status block generation per interrupt. Does anyone have any suggestions or a programming guide for this device?
