Sorry, i explained myself pretty bad. I'm working on an Ethernet driver for
FreeBSD.
The VLAN hw tagging is already working properly, but my nic is capable of
holding a vlan table on hw, filtering vlans on it's own.
I need to find a way to update that hw table.
one way is to recieve a ioctl from the OS of it's vlan table event (add,
remove). I can't find such ioctl.
second is to have a direct access from the driver to the OS vlan table. I'm
not familiar with the interface or if it's possible at all, and that is my
actual question.

Thanks
