[lwip-users] TCPH_OFFSET

[Zschocke, Florian]

tcp.h:

#define TCPH_OFFSET(hdr) (NTOHS((hdr)->_offset_flags) >> 8)

What would be the specific reason that TCPH_OFFSET was defined like this and
that it gets only used as (TCPH_OFFSET >> 4) all over the lwIP code? Is
there a special reason why not simply a TCPH_HDRLEN(hdr) was defined as
follows?

#define TCPH_HDRLEN(hdr) (NTOHS((hdr)->_offset_flags) >> 12)

Florian.
