Description Alexandr 2019-02-21 14:45:59 UTC 
Hello. 
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. 

12.0-RELEASE-p3

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.

Thank you.

The same issue. The NIC going to 'no carrier' for the some time after ifconfig vlan created.  If add next vlan in this time NIC stay 'no carrier'.
The workaround is add pause before/after vlan created.

1. Does the issue reproduce on 12.1-RELEASE?
2. Would it be possible to share part of /etc/rc.conf describing ix configuration?

We have trouble reproducing this bug in our environment.

1. What media type are you using?
2. What type of link partner is used with ix1 interface?
3. Do you force any options in /boot/loader.conf?

1) media: Ethernet autoselect (10Gbase-SR <full-duplex>)
   plugged: SFP/SFP+/SFP28 10G Base-SR (LC)
   vendor: PROLABS PN: EX-SFP-10GE-SR-C
2) juniper ex4550
3) Nothing for devices/network.

Does the configuration also work with the net/intel-ix-kmod [1] port ?
