o call ieee80211_encap in ieee80211_start so frames passed down to drivers
are already encapsulated
o remove ieee80211_encap calls in drivers
o fixup wi so it recreates the 802.3 head it requires from the 802.11
header contents
o move fast-frame aggregation from ath to net80211 (conditional on
IEEE80211_SUPPORT_SUPERG):
- aggregation is now done in ieee80211_start; it is enabled when the
packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
are held on a staging queue according to ieee80211_ffagemax
(net.wlan.ffagemax) to wait for a frame to combine with
- drivers must call back to age/flush the staging queue (ath does this
on tx done, at swba, and on rx according to the state of the tx queues
and/or the contents of the staging queue)
- remove fast-frame-related data structures from ath
- add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
so frames coming through a WDS vap are recognized w/o setting M_WDS
With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

o remove ic_myaddr from ieee80211com
o change ieee80211_ifattach to take the mac address of the physical device
and use that to setup the lladdr.
o replace all references to ic_myaddr in drivers by IF_LLADDR
o related cleanups (e.g. kill dead code)

the related drivers which uses log levels rather than per-facility debugging
flags. This should get rid of contextless messages on the console for people
who have not set (or cleared the default) debugging flags.
packet. Linux, OpenBSD and our iwn(4) all do this. It also results in
a huge performance improvement (and the rejection of a fair number of
apparently-bad packets on receive) on my hardware.
o) Like the wpi(4) driver in OpenBSD, and like our iwn(4), also drop runt
packets.
o) Don't bother doing IFQ_POLL and then IFQ_DRV_DEQUEUE, just do
IFQ_DRV_DEQUEUE outright. This is more similar to how OpenBSD and our
iwn(4) work.

in sta and adhoc modes; this should've been done forever ago as most all
drivers use this hook to set per-station transmit parameters such as for
tx rate control
o adjust drivers to remove explicit calls to the driver newassoc method
some longstanding issues:
o pass the vap since it's now the "coin of the realm" and required
to do things like set initial tx parameters in private node
state for use prior to association
o pass the mac address as cards that maintain outboard station
tables require this to create an entry (e.g. in ibss mode)
o remove the node table reference, we only have one node table
and it's unlikely this will change so this is not needed to
find the com structure
o add IEEE80211_C_STA capability to indicate sta mode is supported
(was previously assumed) and mark drivers as capable
o add ieee80211_opcap array to map an opmode to the equivalent capability bit
o move IEEE80211_C_OPMODE definition to where capabilities are defined so it's
clear it should be kept in sync (on future additions)
o check device capabilities in clone create before trying to create a vap;
this makes driver checks unneeded
o make error codes return on failed clone request unique
o temporarily add console printfs on clone request failures to aid in
debugging; these will move under DIAGNOSTIC or similar before release
- Limit grabbing the lock to SIOCSIFFLAGS.
- Move ieee80211_start_all() to SIOCSIFFLAGS.
- Remove SIOCSIFMEDIA as it is not useful.
- Limit ether_ioctl to only SIOCGIFADDR. SIOCSIFADDR and SIOCSIFMTU have no
affect as there is no input/output path in the vap parent. The vap code
will handle the reinit of the mac address changes.
- Split off ndis_ioctl_80211 as it was getting too different to wired devices.
This fixes a copyout while locked and a lock recursion.

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.

Fix all conventional users of the API to pass the KVA of the buffer

Update the mbuf(9) manual page, which was already out of sync on

Bump __FreeBSD_version to 800016 as there is no way to tell how

This paves the way for giving sendfile(9) a way to wait for the

The call should happen with the driver lock held. We don't hold the driver
lock in newstate as it's a separate thread where we can't sleep (and we only
call wpi_cmd in async mode).

implemented by this driver (or maybe the chipset doesn't support it?)
Removing the flag makes my wpi card work using wpa_supplicant(8) on a
