The basic functions seem to be a perfect fit.
The only bit I'm confused about is what the implication of
The read operations may happen from software interrupt at the
IPL_SOFTCLOCK symbolic level.
is for an application that wants to use this interface. Processing of packets
arriving from hardware interfaces is traditionally run at IPL_SOFTNET, is the
above telling me a reader can't use pserialize(9) if it is running at that
level?
