This is that macro definition:
#define GEN_MLME_EXT_HANDLER(size, cmd) {size, cmd},
struct C2HEvent_Header {
#ifdef __LITTLE_ENDIAN
unsigned int len:16;
unsigned int ID:8;
unsigned int seq:8;
#else
unsigned int seq:8;
unsigned int ID:8;
unsigned int len:16;
#endif
unsigned int rsvd;
};
It's a bit convoluted with regard to my experience. Probably I don't
understand it fully, but it seems to me to not having effects to the code
where I removed its use within core/rtw_cmd.c.
What am I missing?
Thanks for your kind help,
Fabio
