the opportunity to handle an ioctl before generic ifioctl handling
occurs. This will ease extending the kernel and sharing of code
between drivers.
First steps: Make the signature of ifioctl_common() match struct
ifinet->if_ioctl. Convert SIOCSIFCAP and SIOCSIFMTU to the new
ifioctl() regime, throughout the kernel.
Add if_set_sadl() that both sets the link-layer address length and
replaces the current link-layer address with a new one, and use it
throughout the tree.
identify sockaddr_dl abuse that remains in the kernel, especially
the potential for overwriting memory past the end of a sockaddr_dl
with, e.g., memcpy(LLADDR(), ...).
1. Removed the makeoptions line from arch/i386/conf/GENERIC. Now
ndis_driver_data.h is simply copied into the kernel build directory instead
of editing the config file to specify its location.
2. Uncommented lines in files.i386 and files.pci related to NDIS. NDIS will
not be compiled into the kernel unless the two lines are uncommented from
GENERIC (I checked using nm), so there is no reason for this to be commented
out.
3. Added ndiscvt to usr.sbin/Makefile.
so that the location of the ndis_driver_data.h file which is built from
the Windows driver's .inf and .sys files using the ndiscvt utility can be
specified from the kernel configuration file.
arch/i386/conf/GENERIC, arch/i386/conf/files.i386 and dev/pci/files.pci which
can simply be uncommented to compile NDIS into the kernel. I'll write some
documentation on this soon.
Note that NDIS is still somewhat experimental. It is currently tested and
functions relatively well on on two cards:
1. Dell (Broadcom) TrueMobile 1400 Dual Band WLAN Mini-PCI
2. Intel EtherExpress Pro/100
