>Description:
On SuperMicro servers with FreeBSD 8.0-STABLE amd64,i386 with 
different Intel NICs(82573,82546), when I create new vlan on em interface
( ifconfig vlan557 create vlandev em1 vlan 557),
it hangs down and then up with GENERIC kernel and server becomes
inaccessible by ssh, but reply on icmp request with custom kernel.

/var/log/messages:

Nov 23 11:35:49 freebsd kernel: em1: link state changed to DOWN
Nov 23 11:35:49 freebsd kernel: vlan557: link state changed to DOWN
Nov 23 11:35:52 freebsd kernel: em1: link state changed to UP
Nov 23 11:35:52 freebsd kernel: vlan557: link state changed to UP
Nov 23 11:36:09 freebsd kernel: em1: link state changed to DOWN
Nov 23 11:36:13 freebsd kernel: em1: link state changed to UP
>How-To-Repeat:
ifconfig vlan557 create vlandev em1 vlan 557
>Fix:

 This bug looks exactly as mine:
 http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/141843
 
 And IMHO, it's a really critical severity.
