From c530cfb1ce1e8f230744c3f3bd86771f50725053 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 29 Aug 2005 02:15:54 -0300 Subject: [CCID3]: Call sk->sk_write_space(sk) when receiving a feedback packet This makes the send rate calculations behave way more closely to what is specified, with the jitter previously seen on x and x_recv disappearing completely on non lossy setups. This resembles the tcp_data_snd_check code, that possibly we'll end up using in DCCP as well, perhaps moving this code to inet_connection_sock. For now I'm doing the simplest implementation tho.
