The read event demultiplexer
select(2) on Unix FDs
...
Fill up AX.25 interface packet buffers
...
Decode as many packets as possible on each interface
...
Fill up buffers for pending caller reads, open new connections
...
If:
* ax25_select() is called: Notify caller of I/O events
* ax25_read() is called: Provide caller access to requested
buffer region
Buffer may be discarded upon next ax25_read() event, but should not
be discarded after an ax25_select() necessarily.
Most crucially: This sequence of events is triggered by ANY of the I/O calls,
so as to facilitate the same sort of behaviors that one would expect when
letting a kernel thread be responsible for all this activity from a userland
process' perspective. The main difference in behavior in any of these calls is
the result provided to the caller.
