adaptive mutex for the media lock.

remove __packed attribute from struct ieee80211_radiotap_header
and all the structures that include it.

this should not change anything while avoiding packed vs alignment
warnings from GCC 8, and potentially pessimised code generation
due to the packed marker (there are no misaligned members, just
that the per-device parts may end unaligned.)

all consumers of these members are done from the properly aligned
packet members directly, or, as a union with a 64 byte member,
also properly aligned. codegen didn't appear to change, except
for the definition of sizeof(struct driver_[rt]x_radiotap_header)
in debug info, which is not directly used anywhere.

Always use pci_intr_alloc(9)/pci_intr_release(9).

iwm(4) can read the firmware image from disk when interface up.
This change is useful for full-disk encryption environment.

if_iwm use unified establish API.

Use MSI instead of legacy INTx, if available.

should fix PR/49663.

workaround for interrupt coalescing bug not needed on 7265.

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.
