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.

Is that correct? Man pages to check out: vlan(4) and ifconfig(8). I'm pretty sure the vlan tagging feature is per-driver. Also, the vlan(4) list of supported drivers is out of date (for example, em(4) is missing), so be sure to check the man page of your NIC driver. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

HW VLAN Filtering on FreeBSD 6.3 + 7.0
Hi All, I would like to enable my NIC HW VLAN filtering, is there any way for my driver to access the OS vlan table? (something like vlan_group_get_device on linux) I understood from previous investigation that on FreeBSD 6.3 and 7.0 there's no ioctl informing the driver of vlan addition/removal. Is that correct?
