supposed to be opaque to the driver, however it is exposed through several macros which expect certain behavior. In my original implementation, I used the mappedsystemva member of the structure to hold a pointer to the buffer and bytecount to hold the length. It turns out you must use the startva pointer to point to the page containing the start of the buffer and set byteoffset to the offset within the page where the buffer starts. So, for a buffer with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this convention everywhere that ndis_buffers are used. Fortunately, Microsoft defines some macros for initializing and manipulating NDIS_BUFFER structures in ntddk.h. I adapted some of them for use here and used them where appropriate. This fixes the discrepancy I observed between how RX'ed packet sizes were being reported in the Broadcom wireless driver and the sample ethernet drivers that I've tested. This should also help the Intel Centrino wireless driver work. Also try to properly initialize the 802.11 BSS and IBSS channels. (Sadly, the channel value is meaningless since there's no way in the existing NDIS API to get/set the channel, but this should take care of any 'invalid channel (NULL)' messages printed on the console.
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ 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, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). 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 is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/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 NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
