Linux Kernel commit 7e901ee7b6ab "tcp: avoid slow start during fast recovery on new losses", changes the behavior of the test. In net/ipv4/tcp_input.c function tcp_cwnd_reduction() with added variable newly_lost we end up in the following else branch: else if (flag & FLAG_SND_UNA_ADVANCED && !newly_lost). Now sndcnt = sndcnt = min_t(int, delta, max_t(int, tp->prr_delivered
tp->prr_out, newly_acked_sacked) + 1) = 2.
Change the asserted value of tcpi_snd_cwnd from 4 to 5, to match the new kernel behavior.
