Are you sure this condition cannot be reached?

I would suspect you can have available data and the pace_tmr_rxt can be up ...

The code I am removing would only call return, if rsm == NULL and tmr_up == PACE_TMR_RXT. This condition can not be true, since the condition before if (rsm == NULL) reads:

	if (((rsm == NULL) || (tp->t_state < TCPS_ESTABLISHED)) &&
	    (tmr_up == PACE_TMR_RXT)) {
		/* Should be an RXT */
		return;
	}

which means we would return from that condition and never reach the code I am removing.
