I presume abaci is a robot

Perhaps also the robot could look for code immediately above this like:

oct->props[lio->ifidx].fec = var;
if (resp->fec_setting == SEAPI_CMD_FEC_SET_RS)
oct->props[lio->ifidx].fec = 1;
else
oct->props[lio->ifidx].fec = 0;

where a location is immediately overwritten.

so the line
oct->props[lio->ifidx].fec = var;
could be highlighted and perhaps removed
and also perhaps the second test and set block could be written

oct->props[lio->ifidx].fec = resp->fec_setting == SEAPI_CMD_FEC_SET_RS;
