37 * This file implements a translation layer between the BSD networking
38 * infrasturcture and Windows(R) NDIS network driver modules. A Windows
39 * NDIS driver calls into several functions in the NDIS.SYS Windows
40 * kernel module and exports a table of functions designed to be called
41 * by the NDIS subsystem. Using the PE loader, we can patch our own
42 * versions of the NDIS routines into a given Windows driver module and
43 * convince the driver that it is in fact running on Windows.
44 *
45 * We provide a table of all our implemented NDIS routines which is patched
46 * into the driver object code. All our exported routines must use the
47 * _stdcall calling convention, since that's what the Windows object code
48 * expects.

2874 * During system bootstrap, it's impossible to load files
2875 * from the rootfs since it's not mounted yet. We therefore
2876 * offer the possibility of opening files that have been
2877 * preloaded as modules instead. Both choices will work
2878 * when kldloading a module from multiuser, but only the
2879 * module option will work during bootstrap. The module
2880 * loading option works by using the ndiscvt(8) utility
2881 * to convert the arbitrary file into a .ko using objcopy(1).
2882 * This file will contain two special symbols: filename_start
2883 * and filename_end. All we have to do is traverse the KLD
2884 * list in search of those symbols and we've found the file
2885 * data. As an added bonus, ndiscvt(8) will also generate
2886 * a normal .o file which can be linked statically with
2887 * the kernel. This means that the symbols will actual reside
2888 * in the kernel's symbol table, but that doesn't matter to
2889 * us since the kernel appears to us as just another module.

3133 * An NDIS_WORK_ITEM is not the same as a WORK_QUEUE_ITEM. However,
