As of 2.4.32 (don't know about 2.6.x), natsemi still needs to be patched....I just "fixed" it a few weeks ago for a PC Engines WRAP board....VLANs work great now! Oh, note that I changed PKT_BUF_SZ = 1540, not 2064. With PKT_BUF_SZ = 2064 the driver didn't work and generated tons to error messages. (http://www.candelatech.com/~greear/vlan/howto.html#natsemi) But, isn't 1536 big enough, anyhow? I also changed line 1510 to be add 4 bytes additional overhead if the mtu is set larger than 1500 bytes: np->rx_buf_sz = (dev->mtu <= 1500 ? PKT_BUF_SZ : dev->mtu + 32 + 4); -David On Sat, 17 Jun 2006, Peter Stuge wrote: > On Fri, Jun 16, 2006 at 03:01:47PM -0300, Fabio Silva wrote: > > hi, i use netgear with natsemi modules, and a broadcom netExtreme > > gigabit with tg3 module... > > > > its nics are not compatible with vlans on linux ? > > They can be. > > I don't know about tg3 but at least natsemi used to need a patch. > Don't know if the following still applies.
