[PATCH net-next 2/2] net-tcp_bbr: set tp->snd_ssthresh to BDP upon STARTUP exit

Set tp->snd_ssthresh to BDP upon STARTUP exit. This allows us to check if a BBR flow exited STARTUP and the BDP at the time of STARTUP exit with SCM_TIMESTAMPING_OPT_STATS. Since BBR does not use snd_ssthresh this fix has no impact on BBR's behavior. Signed-off-by: Yousuk Seung Signed-off-by: Nea
