net80211: Initialise the interface with a decent link state.
Link state transitions to UP when a node is joined and DOWN when left. This means that with the interface UP, the link state could be UNKNOWN for a while, implying it can be used in BSS mode. Which is of course false.
Add a function to set an initial link state based on the operating mode. Also call this when the operating mode changes.
Basically in BSS and MONITOR it starts off down. BSS will transition UP and DOWN as before, MONITOR will stay down. IBSS, AHDEMO and HOSTAP will remain as link unknown because the state is ..... unknown.

Define and implement a locking protocol for the ifmedia / mii layers: - MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters.
Define and implement a locking protocol for the ifmedia / mii layers: - MP-safe drivers provide a mutex to ifmedia that is used to serialize access to media-related structures / hardware regsiters. Converted drivers use the new ifmedia_init_with_lock() function for this. The new name is provided to ease the transition. - Un-converted drivers continue to call ifmedia_init(), which will supply a compatibility lock to be used instead. Several media-related entry points must be aware of this compatibility lock, and are able to acquire it recursively a limited number of times, if needed. This is a SPIN mutex with priority IPL_NET. - This same lock is used to serialize access to PHY registers and other MII-related data structures.
The PHY drivers are modified to acquire and release the lock, as needed, and assert the lock is held as a diagnostic aid.
The "usbnet" framework has had an overhaul of its internal locking protocols to fit in with the media / mii changes, and the drivers adapted.
USB wifi drivers have been changed to provide their own adaptive mutex to the ifmedia later via a new ieee80211_media_init_with_lock() function. This is required because the USB drivers need an adaptive mutex.
Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv.
mcx also now calls ifmedia_init_with_lock() because it needs to also use an adaptive mutex. The mcx driver still needs to be fully converted to NET_MPSAFE.

Redefine bpf linkage through an always present op vector, i.e. #if NBPFILTER is no longer required in the client. This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized.
Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here.
Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Miscellaneous ath(4) and net80211 updates and bug-fixes coming from sam@ and various open source repositories:
ath(4):
Ignore "phantom" beacon misses: should stabilize connections to access points (no more ceaseless link-UP/DOWN indications). Also, re-synchronize beacon timer using the TSF in the first beacon received after joining a BSS---this should also help suppress spurious beacon misses. I am hopeful that this will help ath(4) lossage reported by perry@ and smb@.
Add new configuration through sysctl.
Use a shorter calibration interval until IQ calibration finishes.
Report antenna noise through radiotap.
Rudiments of Radar Detection / Dynamic Frequency Selection.
Update to HAL version 0.9.16.13.
Update open sources for changes to the HAL API.
Add HALs for additional architectures: add big-endian ELF HALs for sparc64 and for PowerPC. Also add a Alpha HAL. These new HALs are untested under NetBSD.
ath(4) + net80211:
Make the multicast transmit rate configurable by ioctl.

Clarify/fix handling of the current channel: o add ic_curchan and use it uniformly for specifying the current channel instead of overloading ic->ic_bss->ni_chan (or in some drivers ic_ibss_chan) o add ieee80211_scanparams structure to encapsulate scanning-related state captured for rx frames o move rx beacon+probe response frame handling into separate routines o change beacon+probe response handling to treat the scan table more like a scan cache--look for an existing entry before adding a new one; this combined with ic_curchan use corrects handling of stations that were previously found at a different channel o move adhoc neighbor discovery by beacon+probe response frames to a new ieee80211_add_neighbor routine

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field.

Split crypto tx+rx key indices and add a key index -> node mapping table:
Crypto changes: o change driver/net80211 key_alloc api to return tx+rx key indices; a driver can leave the rx key index set to IEEE80211_KEYIX_NONE or set it to be the same as the tx key index (the former disables use of the key index in building the keyix->node mapping table and is the default setup for naive drivers by null_key_alloc) o add cs_max_keyid to crypto state to specify the max h/w key index a driver will return; this is used to allocate the key index mapping table and to bounds check table loookups o while here introduce ieee80211_keyix (finally) for the type of a h/w key index o change crypto notifiers for rx failures to pass the rx key index up as appropriate (michael failure, replay, etc.)
Node table changes: o optionally allocate a h/w key index to node mapping table for the station table using the max key index setting supplied by drivers (note the scan table does not get a map) o defer node table allocation to lateattach so the driver has a chance to set the max key id to size the key index map o while here also defer the aid bitmap allocation o add new ieee80211_find_rxnode_withkey api to find a sta/node entry on frame receive with an optional h/w key index to use in checking mapping table; also updates the map if it does a hash lookup and the found node has a rx key index set in the unicast key; note this work is separated from the old ieee80211_find_rxnode call so drivers do not need to be aware of the new mechanism o move some node table manipulation under the node table lock to close a race on node delete o add ieee80211_node_delucastkey to do the dirty work of deleting unicast key state for a node (deletes any key and handles key map references)
Ath driver: o nuke private sc_keyixmap mechansim in favor of net80211 support o update key alloc api
These changes close several race conditions for the ath driver operating in ap mode. Other drivers should see no change. Station mode operation for ath no longer uses the key index map but performance tests show no noticeable change and this will be fixed when the scan table is eliminated with the new scanning support.

Fix handling of frames sent prior to a station being authorized when operating in ap mode. Previously we allocated a node from the station table, sent the frame (using the node), then released the reference that "held the frame in the table". But while the frame was in flight the node might be reclaimed which could lead to problems. The solution is to add an ieee80211_tmp_node routine that crafts a node that does exist in a table and so isn't ever reclaimed; it exists only so long as the associated frame is in flight.
