Creation/destroying vlans with parent em interface leads to link flap:
root# date;ifconfig vlan4000 create vlan 4000 vlandev em1 10.0.0.1/30;sleep 5;tail -7 /var/log/kern.log

Dec 7 15:18:38 <kern.crit> g kernel: em1: Link is Down
Dec 7 15:18:38 <kern.notice> g kernel: em1: link state changed to DOWN

It's supermicro 5015B-MTB server.
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@pci0:15:0:0: 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
P.S. 7.2R em driver works as expected.
