Macro Definition Documentation

#define ROHC_FEEDBACK_OPT_MAX_OCCURS   100U

Max occurrences of a feedback option in one feedback packet.

Even if the standard says that some options may be present multiple times, don't allow more than a raisonable occurrences. It allows the library to protect itself against abuses.

#define ROHC_FEEDBACK_OPT_MSN   ROHC_FEEDBACK_OPT_SN

The Feedback MSN option (TCP profile)

#define ROHC_FEEDBACK_OPT_MSN_NOT_VALID   ROHC_FEEDBACK_OPT_SN_NOT_VALID

The Feedback MSN-NOT-VALID option (TCP profile)
