Staging: otus: Fix ZM_SEQ_DEBUG macro for no-debug case
Browse files Browse the repository at this point in the history
tcp_seq is only initialised in case where ZM_ENABLE_PERFORMANCE_EVALUATION
is defined. So move the call to ZM_SEQ_DEBUG() and the decleration of
tcp_seq in there too.  This allows ZM_SEQ_DEBUG() to be removed from the
non-ZM_ENABLE_PERFORMANCE_EVALUATION case in the header file.

This resolves several compile warnings for the
non-ZM_ENABLE_PERFORMANCE_EVALUATION case.
However, the ZM_ENABLE_PERFORMANCE_EVALUATION
case seems to be completely broken.
