Re: [dts] [PATCH 1/2] tests/vf_packet_rxtx: fix test case failures in vf_reset

[Joyce Kong <Joyce.Kong@arm.com>]

Hi Marvin,

DUT PF would send dhcp protocol packet to VF before tester transmission, and that's why we need to clear ports  at the start.

Best Regards，
Joyce

Hi Joyce,
Could you please figure out why need to clean the counter before tester transmission? It should be no packet sent to VF before that moment.

Thanks,
Marvin
