Hi,
This patchset refactors mainly for processing rx packets.
Except for devices handled by ALSA bebob and dice drivers, the devices
doesn't take care of the value of syt field of CIP header for playback
timing. To code it explicitly, the new flag is added in 1st patch.
Some of devices based on DICE ASICs supports two pairs of packet
streams. In the case, the sequence of rx packet in the streams should
be different independently so that each of them deliver timing
information from each peer. On the other hand, current implementation
pools the sequence in AMDTP domain, then the rx packets are processed
with the same pool. It is inconvenient and in 2nd patch the pool is
prepared per streams.
The other patches are for my future work.
