As expected, the issue reproduced with commit 53ffcce6fe91 ("ixd: add
devlink support, 2025-11-17").  Applying this patch on top of this commit
allows VFs to receive packets.  Network configuration used:

ip netns add $pf_netns
ip l set $pf netns $pf_netns
ip netns exec $pf_netns ip l set lo up
ip netns exec $pf_netns ip l set $pf address $pf_mac up
ip netns exec $pf_netns ip a add 10.0.0.1/24 dev $pf

ip netns add $vf0_netns
ip l set $vf0 netns $vf0_netns
ip netns exec $vf0_netns ip l set lo up
ip netns exec $vf0_netns ip l set $vf0 up
ip netns exec $vf0_netns ip a add 10.0.0.2/24 dev $vf0

ip netns add $vf1_netns
ip l set $vf1 netns $vf1_netns
ip netns exec $vf1_netns ip l set lo up
ip netns exec $vf1_netns ip l set $vf1 up
ip netns exec $vf1_netns ip a add 10.0.0.3/24 dev $vf1

Assume all variables are known and network namespaces are distinct.
External host was able to successfully ping each 10.0.0.[123].
