mm/page_ref: use page_ref helper instead of direct modification of _count

2016-05-20T02:12:14+00:00

page_reference manipulation functions are introduced to track down
reference count change of the page.  Use it instead of direct
modification of _count.

cfg80211: make wdev_list accessible to drivers

2016-05-12T09:16:40+00:00

There's no harm in having drivers read the list, since they can
use RCU protection or RTNL locking; allow this to not require
each and every driver to also implement its own bookkeeping.

cfg80211: Add option to report the bss entry in connect result

2016-04-26T07:40:12+00:00

Since cfg80211 maintains separate BSS table entries for APs if the same
BSSID, SSID pair is seen on multiple channels, it is possible that it
can map the current_bss to a BSS entry on the wrong channel. This
current_bss will not get flushed unless disconnected and cfg80211
reports a wrong channel as the associated channel.

Fix this by introducing a new cfg80211_connect_bss() function which is
similar to cfg80211_connect_result(), but it includes an additional
parameter: the bss the STA is connected to. This allows drivers to
provide the exact bss entry that matches the BSS to which the connection
was completed.

cfg80211: remove enum ieee80211_band

2016-04-12T13:56:15+00:00

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

wireless: use reset to set mac header

2016-03-05T03:45:13+00:00

Since offset is zero, it's not necessary to use set function. Reset
function is straightforward, and will remove the unnecessary add
operation in set function.
