fc-selenite: src/g23m-fad/ppp/ppp

annotate src/g23m-fad/ppp/ppp_ftxf.c @ 192:4f40ae165be4

abb.c & init.c: sync with Magnetite for Luna additions These Luna target-specific additions are conditionalized on CONFIG_TARGET_LUNA, a C preprocessor symbol that will never be defined in Selenite, hence this change has exactly zero impact on FC Selenite. However, they are being pulled in as a sync in order to keep the diff between Magnetite and Selenite to a minimum; keeping this diff to a minimum increases our opportunities for possible evolution of future FC firmwares.
