rtlwifi: rtl8188ee: initialize packet_beacon

2014-05-13T11:32:53+00:00

commit 328e203fc35f0b4f6df1c4943f74cf553bcc04f8 upstream.

static code analysis from cppcheck reports:

[drivers/net/wireless/rtlwifi/rtl8188ee/trx.c:322]:
  (error) Uninitialized variable: packet_beacon

packet_beacon is not initialized and hence packet_beacon
contains garbage from the stack, so set it to false.

rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbb

2014-05-13T11:32:53+00:00

commit 5f9186990ec4579ee5b7a99b3254c29eda479f36 upstream.

Beginning with kernel 3.13, this driver fails on some systems. The problem
was bisected to:

Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac
Author: Felix Fietkau 
Title: mac80211: send control port protocol frames to the VO queue

There is noting wrong with the above commit. The regression occurs because
V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to
modify the rtl8192se routine that sets the correct transmit queue.

ath9k: fix ready time of the multicast buffer queue

2014-05-13T11:32:52+00:00

commit 3b3e0efb5c72c4fc940af50b33626b8a78a907dc upstream.

qi->tqi_readyTime is written directly to registers that expect
microseconds as unit instead of TU.
When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so
convert it to microseconds before passing it to ath9k_hw.

This should hopefully fix some Tx DMA issues with buffered multicast
frames in AP mode.

iwlwifi: mvm: disable uAPSD due to bugs in the firmware

commit a82dda6cd492b8c88952be6f6527f3656f7ac585 upstream.

The current firmware advertises support for uAPSD, but
critical bugs force us to disable the feature.
When a fixed firmware will be available, we will be able to
re-enable uAPSD.

Revert "net: mvneta: fix usage as a module on RGMII configurations"

2014-05-13T11:32:51+00:00

commit cc6ca3023f2c2bbcd062e9d4cf6afc2ba2821ada upstream.

This reverts commit e3a8786c10e75903f1269474e21fe8cb49c3a670. While
this commit allows to use the mvneta driver as a module on some
configurations, it breaks other configurations even if mvneta is used
built-in.

This breakage is due to the fact that on some RGMII platforms, the PCS
bit has to be set, and on some other platforms, it has to be
cleared. At the moment, we lack informations to know exactly the
significance of this bit (the datasheet only says "enables PCS"), and
so we can't produce a patch that will work on all platforms at this
point. And since this change is breaking the network completely for
many users, it's much better to revert it for now. We'll come back
later with a proper fix that takes into account all platforms.

Basically:

 * Armada XP GP is configured as RGMII-ID, and needs the PCS bit to be
   set.
 * Armada 370 Mirabox is configured as RGMII-ID, and needs the PCS bit
   to be cleared.

And at the moment, we don't know how to make the distinction between
those two cases. One hint is that the Armada XP GP appears in fact to
be using a QSGMII connection with the PHY (Quad-SGMII), but
configuring it as SGMII doesn't work, while RGMII-ID works. This needs
more investigation, but in the mean time, let's unbreak the network
for all those users.
