Multi-bss (aka vap) support for 802.11 devices. Note this includes changes to all drivers and moves some device firmware loading to use firmware(9) and a separate module (e.g. ral). Also there no longer are separate wlan_scan* modules; this functionality is now bundled into the wlan module. Supported by: Hobnob and Marvell Reviewed by: many Obtained from: Atheros (some bits)

* SPDX-License-Identifier: BSD-2-Clause
sys: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Handle ath-specific and WME IE's in adhoc mode. The Adhoc support wasn't parsing and handling the ath specific and WME IEs, thus the atheros vendor support and WME TXOP parameters aren't being copied from the peer. It copies the WME parameters from whichever adhoc node it decides to associate to, rather than just having them be statically configured per adhoc node. This may or may not be exactly "right", but it's certainly going to be more convienent for people - they just have to ensure their adhoc nodes are setup with correct WME parameters. Since WME parameters aren't per-node but are configured on hardware TX queues, if some nodes support WME and some don't - or perhaps, have different WME parameters - things will get quite quirky. So ensure that you configure your adhoc nodes with the same WME parameters. Secondly - the Atheros Vendor IE is parsed and operated on per-node, so this should work out ok between nodes that do and don't do Atheros extensions. Once you see a becaon from that node and you setup the association state, it _should_ parse things correctly. TODO: * I do need to ensure that both adhoc setup paths are correctly updating the IE stuff. Ie, if the adhoc node is created by a data frame instead of a beacon frame, it'll come up with no WME/ath IE config. The next beacon frame that it receives from that node will update the state. I just need to sit down and better understand how that's suppose to work in IBSS mode. Tested: * AR5416 <-> AR9280 - fast frames and the WME configuration both popped up. (This is with a local HAL patch that enables the fast frames capability on the AR5416 chipsets.) PR: kern/165969

[net80211] Add initial U-APSD negotiation support. U-APSD (unscheduled automatic power save delivery) is a power save method that's a bit better than legacy PS-POLL - stations can mark frames with an extra flag that tells the AP to leak out more frames after it sends its own frames rather than needing to send a PS-POLL to get another frame from the AP. Now, this code just handles the negotiation bits; it doesn't actually implement U-APSD. That's up to drivers, and nothing in the tree yet implements this. I /may/ implement this for ath(4) if I eventually care enough but right now I plan on just implementing it for firmware offload based NICs that handle this in the NIC. I'll commit the ifconfig bit after this and I may have some follow-up commits as this gets used more by me in local testing. This should be a glorious no-op for everyone else. If things change for anyone that isn't fixed by a complete recompile then please reach out to me.
