[PATCH v2 0/8] mwifiex patches

[Amitkumar Karwar]

This patch series includes couple of fixes and enhancements.

Changes in v2:
  1) Dropped "[5/9] mwifiex: cfg80211 set_default_mgmt_key handler"
     patch in v1 series. We are working on review comment from Jouni
     Malinen.
  2) Removed MWIFIEX_RX_PKT_DROPPED_IN_FW macro in "[6/9] mwifiex:
     process rxba_sync event" and used NULL pointer to indicate dropped
     packet(Kalle Valo).

Amitkumar Karwar (2):
  mwifiex: fix failed to reconnect after interface disabled/enabled
  mwifiex: remove misleading disconnect message

Ganapathi Bhat (2):
  mwifiex: support random MAC address for scanning
  mwifiex: fix radar detection issue

Karthik D A (2):
  mwifiex: Fixed endianness problem for big endian platform
  mwifiex: add region code information in debugfs

Xinming Hu (2):
  mwifiex: process rxba_sync event
  mwifiex: add HT aggregation support for adhoc mode

[PATCH v2 1/8] mwifiex: Fixed endianness problem for big endian platform

[Amitkumar Karwar]

From: Karthik D A <karthida@marvell.com>

The driver sends and recives information to and from the firmware.
Correct endianness should be ensured as firmware follows little
endian format and host can be little/big endian.

[PATCH v2 2/8] mwifiex: add region code information in debugfs

[Amitkumar Karwar]

From: Karthik D A <karthida@marvell.com>

region code is an EEPROM setting received from firmware. Let's display
this in debugfs along with other information.

[PATCH v2 3/8] mwifiex: fix failed to reconnect after interface disabled/enabled

[Amitkumar Karwar]

Recent patch "mwifiex: fix NULL pointer" skips extended scan event
handling when suspend is in progress. It created a problem for scan
after interface disabled/enabled case.

This patch solves the problem by checking netif_running() status.

[PATCH v2 4/8] mwifiex: support random MAC address for scanning

[Amitkumar Karwar]

From: Ganapathi Bhat <gbhat@marvell.com>

This patch advertises RANDOM_MAC_ADDR feature to cfg80211. It allow the
application to issue scan with a MAC address and mask. Random MACs are
generated and used in probe requests sent for scanning until it is changed
by the application or device is restarted.

[PATCH v2 5/8] mwifiex: process rxba_sync event

[Amitkumar Karwar]

From: Xinming Hu <huxm@marvell.com>

Firmware may filter and drop packets under certain condition, for
example, ARP SA=DA packet. this event will be used to synchronize
the Rx Block Acknowledgment (BA) window bitmap and to fill any holes
in driver side.

[PATCH v2 6/8] mwifiex: remove misleading disconnect message

[Amitkumar Karwar]

Disconnect message in mwifiex_reset_connect_state() would displays
necessary information. We unnecessarily have exactly same message in
cfg80211_disconnect(). As priv->cfg_bssid is cleared at this point of
time, it prints incorrect(all zero) MAC.

This message is removed here.

[PATCH v2 7/8] mwifiex: add HT aggregation support for adhoc mode

[Amitkumar Karwar]

From: Xinming Hu <huxm@marvell.com>

This patch adds HT support for adhoc station. Firmware will upload
ibss sta connect event with beacon data, whenever new station joins
the adhoc network. Driver will check the HT IE and decide whether to
support HT aggreagation or not.

[PATCH v2 8/8] mwifiex: fix radar detection issue

[Amitkumar Karwar]

From: Ganapathi Bhat <gbhat@marvell.com>

It's been observed that firmware sends RADAR detected event without
specifying bss_num/bss_type. Also, the event body is empty.
Currently the event is being ignored by driver.

This patch checks on which interface 11H is active, accordingly fills
bss_num/bss_type and handles the event. Condition
"if (le32_to_cpu(rdr_event->passed))" which always fails is also removed.
