[dpdk-users] problem with an additional MAC address on i40e

[Xing, Beilei]

Hi Kiselev,

What's the firmware version you used? Did you try testpmd?

I tried testpmd with X710 on my side, the steps are:
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start
testpmd> mac_addr add 0 00:00:5E:00:01:0A
testpmd> stop
testpmd> start

After that, packets with destination 01:00:5E:00:00:12 still can be received.

Best Regards
Beilei Xing
