Hello,

I've noticed the following warnings in dmesg and wondered if anyone had ins=
ight on what they mean. It doesn't seem to actually be causing me an obviou=
s problem but I'm not keen on random warnings that I haven't seen before an=
d don't understand.

core2: can't disable some capabilities on igb0.30: 0x400

core2 is a bridge interface that contains a few bhyve guest tap interfaces.=
 It's possible this message is triggered when adding or removing a tap inte=
rface from the bridge. Igb0.30 is a vlan interface. As I'm not an active ke=
rnel developer, actually finding out what capability 0x400 refers to seems =
to be neigh on impossible.

Regards,
Matt Churchyard
