SCTP: Initialize partial_bytes_acked to 0, when all of the data is acked.
According to RFC4960 7.2.2, When all of the data transmitted by the sender has been acknowledged by the recerver, partial_bytes_acked is initialized to 0. This patch conforms to rfc requirement. Without this fix, cwnd might be error incremented. Signed-off-by: Gui Jianfeng <guijianfeng@cn.fujitsu.com> Acked-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.
