Hi Beilei.

> What's the firmware version you used? Did you try testpmd?
I've tried testpmd and didn't find any issues too. Therefore there 
are some specific initialization steps that I do in my application 
that cause the issue, or there are steps that I don't do, but I should.

Also, I've figured out that the address 01:00:5E:00:00:12 has 
nothing to do with my problem. The problem is a VRRP virtual MAC address 
00:00:5E:00:01:0A itself. The problematic packets I can't receive 
have source mac address 00:00:5E:00:01:0A and once that address is added 
to an interface as an additional MAC I stop receiving them on that interface.

Could you please give me any ideas where should I start to find out what 
prevents my application from receiving those packets?


> 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.
