      mac80211: inform the driver about update of dtim_period · c65dd147
      由 Emmanuel Grumbach 提交于 
      Currently, when the driver requires the DTIM period,
mac80211 will wait to hear a beacon before association.
This behavior is suboptimal since some drivers may be
able to deal with knowing the DTIM period after the
association, if they get it at all.

To address this, notify the drivers with bss_info_changed
with the new BSS_CHANGED_DTIM_PERIOD flag when the DTIM
becomes known. This might be when changing to associated,
or later when the entire association was done with only
probe response information.

Rename the hardware flag for the current behaviour to
IEEE80211_HW_NEED_DTIM_BEFORE_ASSOC to more accurately
reflect its behaviour. IEEE80211_HW_NEED_DTIM_PERIOD is
no longer accurate as all drivers get the DTIM period
now, just not before association.

      drivers/net/wireless/iwlegacy/4965-mac.c: adjust duplicate test · 29d7b331
      由 Julia Lawall 提交于 
      Delete successive tests to the same location.  This looks like simple code
duplication.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

      mac80211: split TX aggregation stop action · 18b559d5
      由 Johannes Berg 提交于 
      When TX aggregation is stopped, there are a few
different cases:
 - connection with the peer was dropped
 - session stop was requested locally
 - session stop was requested by the peer
 - connection was dropped while a session is stopping

The behaviour in these cases should be different, if
the connection is dropped then the driver should drop
all frames, otherwise the frames may continue to be
transmitted, aggregated in the case of a locally
requested session stop or unaggregated in the case of
the peer requesting session stop.

Split these different cases so that the driver can
act accordingly; however, treat local and remote stop
the same way and ask the driver to not send frames as
aggregated packets any more.

In the case of connection drop, the stop callback the
driver is otherwise supposed to call is no longer
required.

      drivers/net: Convert compare_ether_addr to ether_addr_equal · 2e42e474
      由 Joe Perches 提交于 
      Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.
