Hi Arend,
As promised, here's the updated patch series for brcmsmac to remove the
tx packet queue, add flow control, and add enhanced debug trace support.
I've broken up the tx rework into multiple patches as you requested.
Most notably I've split out the AMPDU session support into a separate
patch, which should make it easier to review that change. I've done
basic testing of each of the new commits to try and verify that no
obvious regressions are introduced by any of them.
Patch 6 contains the real meat of the tx changes and is still fairly
large. It's going to be difficult to break up this patch any further
though. The most obvious thing to break out at this point would be the
flow control support. However, doing this before removing the tx queue
basically results in throw-away code, and removing it after means that
the commit that removes the tx queue may not work well, potentially
making bisects more difficult. The flow control changes really aren't
that big anyway.
Otherwise the changes are pretty trivial, and functionally the end
result should be identical to v1. I've found that I am still receiving
frames occasionally after stopping a queue so I've kept the headroom in
the tx fifos for now.
Changes since v1:
* Break up the tx path rework as much as possible
* BRCMDBG no longer selects BRCMS_TRACING
* Macro for checking for enabled debug levels has been removed in favor
of open coding the checks
* brcms_debug.[ch] renamed to debug.[ch]
* Debug macros changed to lower-case
* Removed some additional dead code
* A few trivial clean-ups
Thanks,
Seth
