I'm trying to adapt a number of NIC drivers to support 802.1q VLANs, but I'm having problems locating the relevant programming information. I'm particularly interested in the following: Card: SMC9432TX (EtherPower II 10/100) Chip: SMC83c170(?) The search engine on the SMC site just gave me an asp error and there's no obvious developer documentation. Based on a study of if_tx.c, I think VLAN support is just a matter of changing the initialisation for (struct epic_rx_desc).buflen. Card: Intel EtherPower Pro/100+ Chip: 82559 I've found the datasheet at developer.intel.com. It says "set the Long Receive OK bit in the Configuration command (described in the 10/100 Mbit Family Software Developer's Manual)". Unfortunately, I can't find any trace of that manual. There is a VLAN patch at http://www.euitt.upm.es/~pjlobo/fxp-mtu-patch-4.x but it just saves the bad frames, which is different to the comment in the datasheet. Card: DEC DE500-BA Chip: DEC/Intel 21143 The preliminary datasheet is at developer.intel.com. This contains absolutely no information on programming the chip and I can't find any programming information on the intel site. I can't find anything in if_dc.c that suggests any framesize limit, but there is one because it drops long frames. Presumably it needs a bit toggled somewhere. Card: 3Com 3c905-TX (I can't easily check the actual chip). I was unable to locate anything useful on www.3com.com. There is a patch for the 3c905B-TX at http://www.physics.purdue.edu/~csg/xl-vlan.patch but I'm not sure if the max packet size register is also present in the 3c905. (I'm also working on the TI ThunderLAN used as the Compaq Netelligent, but I've managed to find the programming documentation for that). Any assistance would be welcomed.
