      ath9k: unify edma and non-edma tx code, improve tx fifo handling · fce041be
      由 Felix Fietkau 提交于 
      EDMA based chips (AR9380+) have 8 Tx FIFO slots, which are used to fix the
tx queue start/stop race conditions which have to be worked around for
earlier chips by keeping the last descriptor in the queue. The current code
stores all frames that do not fit onto the 8 FIFO slots in a separate
list. Whenever a FIFO slot is freed up, the next frame (or A-MPDU) from the
pending queue gets moved to that slot.

This process is not only inefficient, but also unnecessary. The code can
be improved visibly by keeping the pending queue fully linked, and moving
the contents of the entire queue to a FIFO slot as it becomes available.

This patch makes the necessary changes for that and also merges some code
that was duplicated for EDMA vs non-EDMA. It changes txq->axq_link to point
to the last descriptor instead of the link pointer, so that
ath9k_hw_set_desc_link can be used, which works on all chips.

With this patch, a small performance increase for non-aggregated traffic
was observed on AR9380 based embedded hardware.

      ath9k: fix tx queue index confusion in debugfs code · 5bec3e5a
      由 Felix Fietkau 提交于 
      Various places printing tx queue information used various different ways to
get a tx queue index for printing statistics. Most of these ways were wrong.

ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only
used internally for queue assignment.

One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however
this array uses the ath9k_hw queue number as well.

Fix all of this by always using the ath9k_hw queue number as an index, and
always looking it up by going through sc->tx.txq_map.

      ath9k: remove the virtual wiphy debugfs interface · 34302397
      由 Felix Fietkau 提交于 
      It does not make much sense to keep the current virtual wiphy implementation
any longer - it adds significant complexity, has very few users and is still
very experimental. At some point in time, it will be replaced by a proper
implementation in mac80211.

By making the code easier to read and maintain, removing virtual wiphy support
helps with fixing the remaining driver issues and adding further improvements.
