29d60add09 Fix firmware module dependencies.
malo and mwl use the firmware framework to access firmware images.
Depending on the firmware modules itself is not required and in this
case even wrong because no modules with those names exist.

213eac1f2c Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

affabaa85e - Add a private timer to drive the transmit watchdog instead of using
if_watchdog and if_timer.
- Fix some issues in detach for sn(4), ste(4), and ti(4).  Primarily this
  means calling ether_ifdetach() before anything else.

be5740a255 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

68f7a1034a Overhaul monitor mode handling:
o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO
  and remove explicit bpf support from wireless drivers; drivers now
  use ieee80211_radiotap_attach to setup shared data structures that
  hold the radiotap header for each packet tx/rx
o remove rx timestamp from the rx path; it was used only by the tdma support
  for debugging and was mostly useless due to it being 32-bits and mostly
  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and
  per-com state when there are active taps
o track the number of monitor mode vaps
o use bpf tap and monitor mode vap state to decide when to collect radiotap
  state and dispatch frames; drivers no longer explicitly directly check
  bpf state or use bpf calls to tap frames
o handle radiotap state updates on channel change in net80211; drivers
  should not do this (unless they bypass net80211 which is almost always
  a mistake)
o update various drivers to be more consistent/correct in handling radiotap
o update ral to include TSF in radiotap'd frames
o add promisc mode callback to wi

bda9649894 fix a bug that it passed a incorrect flag BUS_DMA_ALLOCNOW to create
a device specific DMA tag.  On amd64 it could exhaust all of bounce
pages when bus_dma_tag_create(9) is called at malo_pci_attach() then as
result in next turn it returns ENOMEM.  This fix a attach fail on amd64.

ec9a1dd6fa Hoist 802.11 encapsulation up into net80211:
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.

7edd0aa8ef Eliminate ic_myaddr so changing the mac address of a device works correctly:
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)

f663b62128 Minor cleanup of vap create work:
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

3569e353ca 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.
