            Bug ID: 194855
           Summary: VLAN interface MTU does not change on changing the
                    base interface MTU
           Product: Base System
           Version: 10.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: Needs Triage
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: praveenchoudary.gokina@emulex.com

Testmachine details:

OS:  FREEBSD 10.0

We are using Emulex skyhawk adapter.

oce0@pci0:4:0:0:        class=0x020000 card=0xe80110df chip=0x072010df rev=0x10
hdr=0x00
    vendor     = 'Emulex Corporation'
    device     = 'OneConnect NIC (Skyhawk)'
    class      = network
    subclass   = ethernet
    bar   [10] = type Prefetchable Memory, range 64, base 0xfb340000, size
16384, enabled
    bar   [18] = type Prefetchable Memory, range 64, base 0xfb320000, size
131072, enabled
    bar   [20] = type Prefetchable Memory, range 64, base 0xfb300000, size
131072, enabled


Steps to recreate problem:

1. Create a VLAN on a jumbo MTU enabled interface.

ifconfig oce0 mtu 9000 up
ifconfig vlan4 create
ifconfig vlan4 vlan 4 vlandev oce0

2. Change the MTU of the base interface to 1500

ifconfig oce0 mtu 1500

ACTUAL RESULTS :

VLAN interface MTU does not change to 1500, still shows 9000.

EXPECTED RESULT:

VLAN interface MTU should change to the base interface MTU value.
