New Revision: 297006
URL: https://svnweb.freebsd.org/changeset/base/297006
Log:
Add initial 802.11ac IEs and fields.
This is a subset of what's in the linux 802.11ac implementation.
I've verified that the bits that mention an 802.11ac draft are
still the same in 802.11ac-2013 and noted it accordingly.
This is for the most part one big no-op.
