r360902 breaks VLAN interface on if_em (82579LM)

[Martin MATO]

 I was about to fill a bug report about this.
 My network card in that case is a 82574L intel based adapter
As a workaround; bringing down and up the link by ifconfig(8) (and not
by unplug/replug the ethernet cable)
restore the connectivity for the vlan interface (in my case it is an isp
dhcp-based authentication)
and also i narrowed down when the problem appears, and it is at this
revision (r360902)
Do you have filled a bug report?
