When the driver (or most likely firmware) decides which AP to use
for roaming based on internal scan result processing, user space
needs to be notified of PMKSA caching candidates to allow RSN
pre-authentication to be used.

Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).
Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan. Only scan results that
match any of the sets will be returned.
At this point, the set consists of a single parameter, an SSID. This
can be easily extended in the future to support more complex matches.

When the rssi of the current AP drops, both wpa_supplicant and the
firmware may do a background scan to find a better AP and try to
associate. Since firmware based roaming is faster, inform
wpa_supplicant to avoid roaming and let the firmware decide to
roam if necessary.
For fullmac drivers like ath6kl, it is just enough to provide the
ESSID and the firmware will decide on the BSSID. Since it is not
possible to do pre-auth during roaming for fullmac drivers, the
wpa_supplicant needs to completely disconnect with the old AP and
reconnect with the new AP. This consumes lot of time and it is
better to leave the roaming decision to the firmware.

This patch updates the mesh peering frames to the format specified in

- Change RX path to handle new self-protected frames
- Add new Peering management IE
- Remove old Peer Link IE
- Remove old plink_action field in ieee80211_mgmt header

This is needed to match wireless cards with Intersil firmware that have
ID 0x0156:0x0002 and the third ID "Version 01.02". Such cards are
currently matched by orinoco_cs, which doesn't support WPA. They should
be matched by hostap_cs.
The first and the second product ID vary widely, so there are few users
with some particular IDs. Of those, very few can submit a patch for
hostap_cs or write a useful bugreport. It's still important to support
their hardware properly.
With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover

just have to run bcma_bus_register() and it will search for the other
cores, initialize and register them.
