36aedc903e mac80211/cfg80211: HT capabilities for NEW_STA
Allow userspace (e.g., hostapd) to set HT capabilities for associated
STAs. This is based on a patch from Zhu Yi <yi.zhu@intel.com> (only
the NL80211_ATTR_HT_CAPABILITY for NEW_STA part is included here).

154e3af17f p54: fix rssi auto calibration
Ever wondered why the signal was so bad with p54 compared to madwifi, or intel?

Well, if you have revision 1 rssi calibration curve points in your EEPROM, then wonder no more.
The firmware wants a extra 1 byte padding for every curve point. But someone forgot to put
them into the EEPROM's data structure...

So now, big question: what happens when we blindly "memcpy" these data points?

Replace the internal ath9k implementation of multicast/broadcast frame

ieee80211_get_buffered_bc() mechanism. This removes quite a bit of
duplicated functionality and simplifies the driver part.

31ce12fb3e ssb: Clean up extraction of MAC addresses from SPROM
Only rev 1 and 2 ssb SPROMs have fields named et0mac and et1mac;
however, all of the extraction routines extract pseudo data for these
fields from regions that are all 1's resulting in a hardware address
of FF:FF:FF:FF:FF:FF. This patch forces such a fill at the beginning of
the data extraction process, and only does the formal extraction if the
SPROM rev is 1 or 2.

b569d5a134 dccp: Empty the write queue when disconnecting
dccp_disconnect() can be called due to several reasons:

 1. when the connection setup failed (inet_stream_connect());
 2. when shutting down (inet_shutdown(), inet_csk_listen_stop());
 3. when aborting the connection (dccp_close() with 0 linger time).

In case (1) the write queue is empty. This patch empties the write queue,
if in case (2) or (3) it was not yet empty.

This avoids triggering the write-queue BUG_TRAP in sk_stream_kill_queues()
later on.

It also seems natural to do: when breaking an association, to delete all
packets that were originally intended for the soon-disconnected end (compare
with call to tcp_write_queue_purge in tcp_disconnect()).

1efa6bbac8 dccp: Silently ignore options with nonsensical lengths
This updates the option-parsing code with regard to RFC 4340, 5.8:
 "[..] options with nonsensical lengths (length byte less than two or more
  than the remaining space in the options portion of the header) MUST be
  ignored, and any option space following an option with nonsensical length
  MUST likewise be ignored."

Hence in the following cases erratic options will be ignored:
 1. The type byte of a multi-byte option is the last byte of the header
    options (i.e. effective option length of 1).
 2. The value of the length byte is less than the minimum 2. This has been 
    changed from previously 3: although no multi-byte option with a length
    less than 3 yet exists (cf. table 3 in 5.8), a length of 2 is valid.
    (The switch-statement in dccp_parse has further per-option length checks.)
 3. The option length exceeds the length of the remaining option space.

33c449675c dccp: Always generate a Reset in response to option errors
RFC4340 states that if a packet is received with an option error (such as a
Mandatory Option as the last byte of the option list), the endpoint should
repond with a Reset.

In the LISTEN and RESPOND states, the endpoint correctly reponds with Reset,
while in the REQUEST/OPEN states, packets with option errors are just ignored.

The packet sequence is as follows:

Case 1:

  Endpoint A                           Endpoint B
  (CLOSED)                             (CLOSED)

               <----------------       REQUEST

  RESPONSE     ----------------->      (*1)
  (with invalid option)
               <----------------       RESET
                                       (with Reset Code 5, "Option Error")

  (*1) currently just ignored, no Reset is sent

Case 2:

  Endpoint A                           Endpoint B
  (OPEN)                               (OPEN)

  DATA-ACK     ----------------->      (*2)
  (with invalid option)
               <----------------       RESET
                                       (with Reset Code 5, "Option Error")

  (*2) currently just ignored, no Reset is sent

This patch fixes the problem, by generating a Reset instead of silently
ignoring option errors.
