The library built in this directory is a host side library, not for the target.
This library implements some functions for handling packet exchanges with GPF,
and it will be linked by some of the programs in the rvinterf suite.

It needs to be noted that the RVTMUX channel belonging to GPF was named
RVT_L23_HEADER by TI, and as a result, I thought that these packets related
specifically to the higher layers of the protocol stack.  But now we know that
hierarchically speaking, GPF sits *below* L1, not above, and GPF packets should
not be automatically associated with G23.  This realization was made fairly
late, thus "g23" appears in a bunch of function names, and in the name of this
library.
