DPDK Experts,

When I run I40E host PF driver with DPDK VF Driver in VM, I see an issue wh=
ere packets are received in bunch of 4s. See below

But the same problem does not show up when run with DPDK PF testpmd with DP=
DK VF in VM.=20

Since we would like to have I40e regular driver work with DPDK VF, Can one =
please point to code change that was made in DPDK PF (testpmd) to make this=
 happen?=20

thanks,
shanar.

Inside VM:
./examples/l2fwd/l2fwd/x86_64-native-linuxapp-gcc/app/l2fwd -c 0xb -n 4 -- =
-p 0x3
