Hi all,

This new version addresses the feedback from v1 and fixes a bug on capture
mode. Code-wise, the changes are very trivial, no major diffs. Below follows
the highlights:

  * Standard headers like linux/if_ether.h are now checked by configure script.
  * The 'static' modifier was added to array variables in aaf_hw_constraint().
  * aaf_close() callback was simplified.
  * aaf_rx_pdu() was modified so it doesn't return an error in case the number
    of bytes read by recv() is different from aaf->pdu_size. This is an
    expected situation and it means the received AVTPDU doesn't belong to the
    AAF stream the plugin is interested in so it should simply drop that
    AVTPDU. This fixes a bug when running multiple streams (with different
    AVPTU sizes) concurrently.

Additionally, this new version improves the instructions in doc/aaf.txt in
order to make it easier to test the plugin. Anyone should be able to test it
just by copying and pasting the instructions.

To recap what has been discussed about the plugin so far, check the comments in
RFC and PATCH series archive [1-3]. All versions of this series can be also
found in my alsa-plugins tree in github [4].

Regards,

Andre
