[RFC V2 0/3] nl80211: allow configuration of BSS selection

[Arend van Spriel <arend@broadcom.com>]

This patch series adds support for configuration of BSS selection done by
the driver and/or firmware. It allows user-space to pass selection criteria
with the NL80211_CMD_CONNECT using NL80211_ATTR_BSS_SELECT. When user-space
does provide this attribute and no explicit BSSID is provided it will pass
the BSS selection criteria to the driver if the driver supports it.

When multiple BSS-es are found belonging to the same ESS, ie. Infra-BSS with
same SSID, the criteria can be used to select a BSS. The criteria defined are:

1. RSSI based selection.
2. Band selection, RSSI based selection.
3. RSSI adjustment in given band, RSSI based selection.

V2:
 - incorporate comments from Johannes Berg (may have missed some).
 - split nl80211 patch in two separate patches.

Arend van Spriel (3):
  nl80211: add extended feature for BSS selection support
  nl80211: add bss selection attribute to CONNECT command
  brcmfmac: add support for nl80211 BSS_SELECT feature
