I've tested with tcpdump, and here's what i found:

Host interfaces:
em0 up
vlan22 10.15.15.1/24 vlandev em0 vlan22
epair0a - part of epair for jail foo
bridge0 addm epair0 addm em0

Jail foo interfaces:
epair0b up (vnet interface)
vlan22 10.15.15.2/24 vlandev epair0b vlan22

While pinging from jail IP 10.15.15.1 tcpdump see ARP packets all way 
through to em0:

# tcpdump -i em0 -e | grep 10.15.
18:18:37.194891 02:62:bb:b6:19:0b (oui Unknown) > Broadcast, ethertype 
802.1Q (0x8100), length 46: vlan 22, p 0, ethertype ARP, Request who-has 
10.15.15.1 tell 10.15.15.2, length 28

10.15.15.1 tell 10.15.15.2, length 28

But for some reason they're not reaching host's vlan22 interface which 
have "vlandev em0 vlan 22" config. How could it be?

Ipfw is not enabled.
