This assumption is valid because TCPCB_EVER_RETRANS does\nnot leave holes but each non-SACKed segment is rexmitted\nin-order.\n\nCheck for retrans_out \u003e 1 avoids more expensive walk through the\nskb list, as we can know the result beforehand: F-RTO will not be\nallowed.\n\nSACKed skb can turn into non-SACked only in the extremely rare\ncase of SACK reneging, in this case we might fail to detect\nretransmissions if there were them for any other than head. To\nget rid of that feature, whole rexmit queue would have to be\nwalked (always) or FRTO should be prevented when SACK reneging\nhappens. Of course RTO should still trigger after reneging which\nmakes this issue even less likely to show up.
