If in rc.conf is configured more than 1 vlan, Freebsd loads with 'no carrier'.
If 1 vlan is configured or without vlan NIC works fine.
ix0@pci0:1:0:0: class=0x020000 card=0x065915d9 chip=0x15578086 rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = '82599 10 Gigabit Network Connection'
class = network
subclass = ethernet
ixgbe_driver_version = "4.0.1-k"
It can be fixed by installation the driver Version - 3.3.6 from downloadcenter.intel.com.
After that NIC works fine.
