freebsd kernel with SKQ

- probe for PHYs by checking the BMSR (phy status) register instead of the vendor ID register. - fix the autonegotiation routine so that it figures out the autonegotiated modes correctly. - add tweaks to support the Olicom OC-2326 now that I've actually had a chance to test one o Olicom appears to encode the ethernet address in the EEPROM in 16-bit chunks in network byte order. If we detect an Olicom card (based on the PCI vendor ID), byte-swap the station address accordingly. XXX The Linux driver does not do this. I find this odd since the README from the Linux driver indicates that patches to support the Olicom cards came from somebody at Olicom; you'd think if anyone would get that right, it'd be them. Regardless, I accepted the word of the disgnoatic program that came bundled with the card as gospel and fixed the attach routine to make the station address match what it says. o The version of the 2326 card that I got for testing is a strange beast: the card does not look like the picture on the box in which it was packed. For one thing, the picture shows what looks like an external NS 83840A PHY, but the actual card doesn't have one. The card has a TNETE100APCM chip, which appears to have not only the usual internal tlan 10Mbps PHY at MII address 32, but also a 10/100 PHY at MII address 0. Curiously, this PHY's vendor and device ID registers always return 0x0000. I suspect that this is a mutant version of the ThunderLAN chip with 100Mbps support. This combination behaves a little strangely and required the following changes: - The internal PHY has to be enabled in tl_softreset(). - The internal PHY doesn't seem to come to life after detecting the 100Mbps PHY unless it's reset twice. - If you want to use 100Mbps modes, you have to isolate the internal PHY. - If you want to use 10Mbps modes, you have to un-isolate the internal PHY. The latter two changes are handled at the end of tl_init(): if the PHY vendor ID is 0x0000 (which should not be possible if we have a real external PHY), then tl_init() forces the internal PHY's BMCR register to the proper values. |

This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.11 1997/08/09 14:36:20 jkh Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
