Name:We follow the spirit of RFC2861 to validate cwnd but implement a more* flexible approach. The RFC suggests cwnd should not be raised unless* it was fully used previously. And that's exactly what we do in* congestion avoidance mode

Proto:static inline bool tcp_is_cwnd_limited(const struct sock *sk)

Type:bool

Parameter:

TypeParameterName
const struct sock *sk
1257  tp = tcp_sk(sk)
1260  If tcp_in_slow_start(tp) Then Return Sending congestion window < 2 * max packets_out in last window
1263  Return forward progress limited by snd_cwnd?
