644e8c0739 brcmsmac: restructure info->control.sta handling as it is goning to be removed soon.
brcmsmac uses info->control.sta while doing ampdu aggregation. This patch
changes the usage of the structure info->control.sta, as it is going to be
removed soon from struct ieee80211_tx_info. This patch is a pre-requisit in
order to add transmission power control (TPC) to the mac80211 subsystem.

2b0a53d51b brcm80211: smac: only print block-ack timeout message at trace level
In regular use block-ack timeouts can happen so it does not make
sense to fill the log with these messages.

85091fc0a7 brcm80211: smac: fix endless retry of A-MPDU transmissions
The A-MPDU code checked against a retry limit, but it was using
the wrong variable to do so. This patch fixes this to assure
proper retry mechanism.

This problem had a side-effect causing the mac80211 flush callback
to remain waiting forever as well. That side effect has been fixed
by commit by Stanislaw Gruszka:

8ae746543c brcm80211: Use normal DEBUG define
Current CONFIG_BRCMDBG flag when enabled does not
necessarily enable proper pr_debug output when
DEBUG is not also enabled.

Remove BCMDBG define and just use DEBUG instead.

16d2812e9e brcm80211: smac: use bcma core register access functions for 802.11 core
The driver now uses the bcma register access functions to read and
write the registers on the 802.11 core. The dma and phy code need
to be modified next and access to the other cores. That will be done
in coming patches.

ad4d71f69e brcm80211: smac: remove usage of brcmu_pkttotlen
The function brcmu_pkttotlen calculates the total length of a sk_buff
chain following the next pointer. In brcmsmac this is not needed as
in each place where it was used the provided sk_buff had a NULL pointer
as next field value.
