e5d6eb8305 mac80211: fix max HT rate processing on mac80211
The max MCS index is 76, fix the higher check to allow through
frames received at MCS 76. This is a non-issue for current drivers
as MCS 76 is only possible with a device supporting 4 spatial
streams.

While at it change the WARN_ON() on invalid HT rates to a WARN()
to provide more useful information. This will help debug issues
when the driver is passing up a bogus HT rate value.

The rate must map to a valid MCS index which can be any of the
values in the set [0 - 76] (inclusive).

statements in the rt2x00 are meaningless, as the rt2x00 project is

748d451028 ath9k_common: clarify and correct jumbogram processing
Jumbograms are frames put together linked together through
more than one descriptor. For example ath9k_htc will use this
to send from the target a large frame split up into 2 or more
segments. The driver then would be in charge of putting the
frame back together.

When jumbograms are constructed the rx_stats->rs_more will
bet set and rx_stats->rs_status will not have any valid content
as the actual status will only be avialable at the end of
the chained descriptors.

db86f07ec6 ath9k_common: add new module to share 802.11n driver helpers
ath9k and ath9k_htc share a lot of common hardware characteristics.
They only differ in that ath9k_htc works with a target CPU and ath9k
works directly with the hardware. ath9k_htc will do *some* things in
the firmware, but a lot of others on the host.

The common 802.11n hardware code is already shared through the ath9k_hw
module. Common helpers amongst all Atheros drivers can use the ath module,
this includes ath5k and ar9170 as users. But there is some common driver
specific helpers which are not exactly hardware code which ath9k and
ath9k_htc can share. We'll be using ath9k_common for this to avoid
bloating the ath module and the common 802.11n hardware module ath9k_hw.

We start by sharing skb pre and post processing in preparation for a hand
off to mac80211.

5ca42627f3 ath9k: avoid the copy skb->cb on every RX'd skb
The skb->cb (control buffer, 48 bytes) is available to the skb
upon skb allocation. You can fill it up imediately after skb
allocation. ath9k was copying onto the skb->cb the data from the
processed skb for mac80211 from a stack struct ieee80211_rx_status
structure. This is unnecessary, instead use the skb->cb for the
rx status immediately after the skb becomes available and DMA
synched.

Additionally, avoid the copy of the skb->cb also for virtual wiphys
as skb_copy() will copy over the skb->cb for us as well.
