>Description:
Using this em(4) cards:

em0@pci0:13:0:0:        class=0x020000 card=0x108c15d9 chip=0x108c8086 rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel Corporation 82573E Gigabit Ethernet Controller (Copper) (82573E)'
    class      = network
    subclass   = ethernet
em1@pci0:14:0:0:        class=0x020000 card=0x109a15d9 chip=0x109a8086 rev=0x00 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel PRO/1000 PL Network Adaptor (82573L)'
    class      = network
    subclass   = ethernet

I configured a lagg interface (lagg0) to lacp on two em interfaces and Cisco, and configured a vlan with "vlandev lagg0" (vlan3). Under 7.2-STABLE on this host, there were no issues. Upon upgrading to 8.0-STABLE, the host became unable to communicate through either vlan interface. The host is still able to receive traffic; only outbound traffic are problematic, because packets not transfered on target hosts and on port of Cisco where host connected (two gi and etherchannel po) not seeing any mac.

>How-To-Repeat:
Boot a system containing two em(4) interfaces (may need to be the above chipset) with no network configuration in rc.conf and execute the following commands as root:

# ifconfig em0 link0 up
# ifconfig em1 link0 up
# ifconfig lagg0 create laggproto lacp laggport em0 laggport em1 up
# ifconfig vlan3 create vlan 3 vlandev lagg0
# ifconfig vlan3 <ip>/<mask> up

Generate traffic on the configured IP network (e. g., ping).

This does not sound i386-specific.

 Please see also kern/141646.  This may well be the same issue.

State-Changed-Why:  
May be the same as kern/141646, which is fixed in 8.2.  To the 
original submitter, can you test the patch from that PR or test 
FreeBSD 8.2 or later?

Responsible-Changed-Why:  
It sounds like this is a problem with lagg(4) not em(4) and so shouldn't 
be assigned to jfv.
