One small suggestion: please include prerequisites in the 0/8 cover letter 
(e.g., `iproute2` version and that commands need root privileges), so testers 
don’t miss that.

Roger that; I plan to use following:

To reproduce the issue have a E810 ($pfa) connected to another adapter
($pfb), then:

    # echo 2 >/sys/class/net/$pfa/device/sriov_numvfs
    # ip l set $pfa vf 0 vlan 4
    # ip l set $pfa vf 1 vlan 7
    # ip l set $pfa_vf0 netns $pfa_vf0_netns up
    # ip l set $pfa_vf1 netns $pfa_vf1_netns up
    # ip netns exec $pfa_vf0_netns ip a add 10.0.0.1/24 dev $pfa_vf0
    # ip netns exec $pfa_vf1_netns ip a add 10.0.0.2/24 dev $pfa_vf1

And for the $pfb:

    # echo 2 >/sys/class/net/$pfb/device/sriov_numvfs
    # ip l set $pfb vf 0 trust on spoof off vlan 4
    # ip l set $pfb vf 1 trust on spoof off vlan 7
    # ip l add $br type bridge
    # ip l set $pfb_vf0 master $br up
    # ip l set $pfb_vf1 master $br up
    # ip l set $br up

We expect $pfa_vf0 to be able to reach $pfa_vf1 through the $br on
the link partner.  Instead, ARP is unable to resolve 10.0.0.2/24.
ARP request is fine because it's broadcasted and bounces off $br, but
ARP reply is stuck in the internal switch because the destination MAC
matches $pfa_vf0 and filter restricts it to loopback.

In testing I used: ip utility, iproute2-6.1.0, libbpf 1.3.0

Otherwise, the instructions are fine from my side. Please keep my:
