description:
Add a driver for Intel Centrino 7260 and similar wireless cards.
Supported devices should more or less match ones supported
by the Linux iwlwifi mvm driver. Sponsored by genua mbh for OpenBSD.
This is probably the world's first Canadian cross device driver: it was
created for OpenBSD by writing and porting a NetBSD driver which was
developed in a rump kernel in Linux userspace.
Note: I don't have access to the hardware anymore, so this version is
not tested and not enabled by default. While I tried to be careful in
adding the NetBSD bits back, it's probable that there's a snafu or two.
Feel free to send private email in case you have the hardware and there
are issues.
