-The library built in this directory is a host side library, not for the target.

-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

-hierarchically speaking, GPF sits *below* L1, not above, and GPF packets should
