freebsd kernel with SKQ

in 4 byte chunks. It turns out that with the 82c169C on the Netgear FA-310TX Rev D2, if you tell the chip you have reserved a buffer of 1518 bytes, it will actually treat it as 1516 bytes since 1518 is divisible by four. Consequently, a packet of 1514 bytes will always end up consuming two buffers: the last coupleof bytes will spill over into the next descriptor. This causes the pn_rx_bug_war() routine to trip unnecessarily. I'm not sure if the 82c169B or 82c168 chips behave the same way; I'll have to check them. In any case, this change should work just as well with them. Note that the FA-310TX Rev D2 also has a Broadcom PHY instead of a Level One LXT970 PHY, however this shouldn't make any difference as far as the driver is concerned. This change also allows me to do a way with one rounding overation in pn_rx-buf_war(). |

UPDATING |
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm 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).
