Commit Message

Takashi Sakamoto Dec. 11, 2018, 10:17 a.m. UTC 
As long as investigating packet dumps from Fireface 400/800, a register
to receive asynchronous transactions for MIDI messages is the same. For
Fireface 800, minor register is used.

This commit declares macros for the transactions and obsoletes
model-specific parameters.
