[PATCH net-next 1/3] mptcp: use mptcp_win_from_space helper

From: Matthieu Baerts (NGI0)
Date: Wed Jun 05 2024 - 03:18:05 EST


From: Geliang Tang <tanggeliang@xxxxxxxxxx>

The MPTCP dedicated win_from_space helper mptcp_win_from_space() is defined
in protocol.h, use it in mptcp_rcv_space_adjust() instead of using the TCP
one. Here scaling_ratio is the same as msk->scaling_ratio.
