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;
			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;
