[PATCH wireless-next 0/8] Adding NO_STA flag and reworking RX link resolution

[Benjamin Berg <benjamin@sipsolutions.net>]

From: Benjamin Berg <benjamin.berg@intel.com>

Hi,

This patchset refactors the RX link resolution a bit to fix some issues
where mac80211 might accept frames on the wrong link and incorrectly
translate the address. It also adds a new NL80211_ATTR_FRAME_CMD_NO_STA
flag so that userspace can know whether address translation was done by
the kernel on RX and can also prevent address translation for management
frames during TX.

This together should be enough to fix the existing issues in hostapd
where stations that are still associated try to authenticate again but
hostapd for example ends up sending the frame to an old link address.

Benjamin

Changes in v1:
 * Add NAN_DATA interface handling
 * Handle NO_STA flag correctly for NAN
 * Fixed forwarding of station parameter
 * Rebase and other small fixes

Changes in RFCv2:
 * Port other drivers to new API (untested)
 * Fix a checkpatch warning

Benjamin Berg (8):
  wifi: iwlwifi: use link_sta internally to the driver
  wifi: mac80211: change public RX API to use link stations
  wifi: mac80211: refactor RX link_id and station handling
  wifi: mac80211: rework RX packet handling
  wifi: cfg80211: add attribute for TX/RX denoting there is no station
  wifi: mac80211: report to cfg80211 when no STA is known for a frame
  wifi: mac80211: pass station to ieee80211_tx_skb_tid
  wifi: mac80211: pass error station if non-STA transmit was requested
