An IPA endpoint has a sequencer that must be configured based on how
the endpoint is to be used. Currently the IPA code programs the
sequencer type by splitting a value into four 4-bit nibbles. Doing
that doesn't really add much value, and regardless, a better way of
splitting the sequencer type is into two halves--the lower byte
describing how normal packet processing is handled, and the next
byte describing information about processing replicas.
So split the sequencer type into two sub-parts: the sequencer type
and the replication sequencer type. Define the values supported for
the "main" sequencer type, and define the values supported for the
replication part separately.
In addition, the sequencer type names are quite verbose, encoding
what the type includes, but also what it *excludes*. Rename the
sequencer types in a way that mainly describes the number of passes
that a packet takes through the IPA processing pipeline, and how
many of those passes end by supplying the processed packet to the
microprocessor.
The result expands the supported types beyond what is required for
now, but simplifies the way these are defined.
