Date: Sun, 7 Sep 2008 13:58:20 +0300 From: "Rami Rosen" <roszenrami@...il.com> To: "Eli Cohen" <eli@....mellanox.co.il> Cc: netdev@...r.kernel.org Subject: Re: add/delete VLANs programatically Hi, -It seems to me that it is possible. - If you look at the ordinary way in which user space add/deletes VLAN, you will see that this is performed by ioctls (SIOCSIFVLAN for adding /removing with ADD_VLAN_CMD or DEL_VLAN_CMD). - It is in performed by user space vconfig - VLAN (802.1q) configuration program. - When looking at how these IOCTLs are handled in the kernel, you will see that this is done by vlan_ioctl_handler() in net/8021q/vlan.c. -If you look there, you will see that eventually adding a vlan is done in the kernel by register_vlan_device(net_device, VLAN ID); end deleing a vlan is done in the kernel by calling unregister_vlan_dev(net_device) So it seems to me possible, though I did not try it.
