ssb: Make bus registration failure not be silent

In kernel Bugzilla #15825, a case where routine ssb_bus_pcibus_register()
fails silently is reported. The cause for the failure is still being
investigated; however, the diagnosis would be easier if the failure
had been reported.

Quote from comment #17:
"The problem is the innocent looking moving of the tx processing to
 after the rx processing in the tasklet. Quoting from the changelog:
  This patch does it the same way, except that it also prioritize
  rx data processing, simply because tx routines *can* wait.

 This is causing an issue with us referencing already freed memory,
 because some skb's we transmit, we immediately receive back, such
 as those for reading the eeprom (*) and getting stats.

 What can happen because of the moving of the tx processing to after
 the rx processing is that when the tasklet first runs after doing a
 special skb tx (such as eeprom) we've already received the answer
 to it.

 Then the rx processing ends up calling p54_find_and_unlink_skb to
 find the matching tx skb for the just received special rx skb and
 frees the tx skb.

 Then after the processing of the rx skb answer, and thus freeing
 the tx skb, we go process the completed tx ring entires, and then
 dereference the free-ed skb, to see if it should free free-ed by
 p54p_check_tx_ring()."

mac80211: Fix sta->last_tx_rate setting with no-op rate control devices

The sta->last_tx_rate is traditionally updated just before transmitting a
frame based on information from the rate control algorithm. However, for
hardware drivers with IEEE80211_HW_HAS_RATE_CONTROL this is not performed,
as the rate control algorithm is not executed, and because the used rate is
not known before the frame has actually been transmitted.

This causes atleast a fixed 1Mb/s to be reported to user space. A few other
instances of code also rely on this information.

Fix this by setting the sta->last_tx_rate in tx_status handling. There, look
for last rates entry set by the driver, and use that as value for
sta->last_tx_rate.

is present before attempting to read it.  This avoids those hard hangs
on those devices with no SPROM attached to their SSB bus.  The

ath9k: Group Key fix for VAPs

When I set up multiple VAPs with ath9k, I encountered an issue that
the traffic may be lost after a while.

The detailed phenomenon is
1. After a while the clients connected to one of these VAPs will get
into a state that no broadcast/multicast packets can be transfered
successfully while the unicast packets can be transfered normally.
2. Minutes latter the unitcast packets transfer will fail as well,
because the ARP entry is expired and it can't be freshed due to the
broadcast trouble.

It's caused by the group key overwritten and someone discussed this
issue in ath9k-devel maillist before, but haven't work out a fix yet.

I referred the method in madwifi, and made a patch for ath9k.
The method is to set the high bit of the sender(AP)'s address, and
associated that mac and the group key. It requires the hardware
supports multicast frame key search. It seems true for AR9160.

Not sure whether it's the correct way to fix this issue. But it seems
to work in my test. The patch is attached, feel free to revise it.

ath9k_hw: Use buffered register writes

This patch adds macros at certain places
which could be optimized for multiple register writes.

The performance of ath9k_htc improves considerably,
especially reducing the latency involved in a scan run.

ath9k_hw: Relocate Opmode initialization

Programming the opmode in the HW can be done
before the assoc_id and STA_ID registers are
setup. This helps ath9k_htc when multiple register
writes are used.

This patch adds support for writing multiple registers
in a single USB command.

register writes would be modified to make use of this
in subsequent patches.

Benoit Papillault [Thu, 15 Apr 2010 22:07:26 +0000]
ath5k/ath9k: Fix 64 bits TSF reads

According to tests, both TSF lower and upper registers kept counting, so
the higher part could have been updated after the lower part has been
read, as shown in the following log where the upper part is read first
and the lower part next.

tsf = {00000003-fffffffd}
tsf = {00000003-00000001}
tsf = {00000004-0000000b}

This patch corrects this by checking that the upper part has not been
changed while the lower part was read. It has been tested in an IBSS
network where artifical IBSS merges have been done in order to trigger
hundreds of rollover for the TSF lower part.

It follows the logic mentionned by Derek, with only 2 register reads
needed at each additional steps instead of 3 (the minimum number of
register reads is still 3).
