in order to query the underlying Windows driver for the station address and some other properties. There is a slim chance that the card may receive a packet and indicate it up to us before ndis_attach() can call ndis_halt_nic(). This is bad, because both the softc structure and the ifnet structure aren't fully initialized yet: many pointers are still NULL, so if we make it into ndis_rxeof(), we will panic. To fix this, we need to do the following: - Move the calls to IoAllocateWorkItem() to before the call to ndis_init_nic(). - Move the initialization of the RX DPC and status callback function pointers to before ndis_init_nic() as well. - Modify ndis_rxeof() to check if the IFF_DRV_RUNNING flag is set. If it isn't, we return any supplied NDIS_PACKETs to the NIC without processing them. This fixes a crash than can occur when activating a wireless NIC in close proximity to a very busy wireless network, reported by Ryan Beasley (ryan%^$!ATgoddamnbastard-****!!!DOTorg.

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.
