      wl1251: fix oops on early interrupt · f380f2c4
      由 Grazvydas Ignotas 提交于 
      This driver disables interrupt just after requesting it and enables it
later, after interface is up. However currently there is a time window
between request_irq() and disable_irq() where if interrupt arrives, the
driver oopses because it's not yet ready to process it. This can be
reproduced by inserting the module, associating and removing the module
multiple times.

Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().

      wlcore/wl12xx: implement better beacon loss handling · 5f561f68
      由 Bartosz.Markowski@tieto.com 提交于 
      Make use of REGAINED_BSS_EVENT and instead of reporting connection
loss immediately on each BEACON_LOSE event, try if not regained
in reasonable period of time.

      wlcore: fix size of two memset's in wl1271_cmd_build_arp_rsp() · 161f17b5
      由 Jesper Juhl 提交于 
      We currently do this:

int wl1271_cmd_build_arp_rsp(struct wl1271 *wl, struct wl12xx_vif *wlvif)
...
      struct wl12xx_arp_rsp_template *tmpl;
      struct ieee80211_hdr_3addr *hdr;
...
      tmpl = (struct wl12xx_arp_rsp_template *)skb_put(skb, sizeof(*tmpl));
      memset(tmpl, 0, sizeof(tmpl));
...
      hdr = (struct ieee80211_hdr_3addr *)skb_push(skb, sizeof(*hdr));
      memset(hdr, 0, sizeof(hdr));
...

I believe we want to set the entire structures to 0 with those
memset() calls, not just zero the initial part of them (size of the
pointer bytes).

      wireless: TI wlxxx depends on MAC80211 · bd28a58f
      由 Randy Dunlap 提交于 
      wl12xx build fails with many undefined symbol errors when MAC80211
and CFG80211 are not enabled, so make WLCORE and WL12XX depend
on MAC80211 (which already depends on CFG80211).

      wl12xx: support wowlan wakeup patterns · b95d7cef
      由 Eyal Shapira 提交于 
      Use FW RX data filters to support cfg80211 wowlan wakeup patterns.
This enables to wake up the host from suspend following detection
of certain configurable patterns within an incoming packet.
Up to 5 patterns are supported. Once the host is resumed
any configured RX data filter is cleared.
A single pattern can match several bytes sequences with different
offsets within a packet.
