Very little point of having 32-bit snd_cnwd if this is not 32-bit as well, as a number of snd_cwnd incrementation formulas assume that snd_cwnd_cnt can be at least as large as snd_cwnd.
Whether 32-bit is useful was discussed when e0ef57cc56c3c96 was made: http://marc.info/?l=linux-netdev&m=117218144409825&w=2 Signed-off-by: Ilpo Järvinen <[EMAIL PROTECTED]> --- include/linux/tcp.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/include/linux/tcp.h b/include/linux/tcp.h index c5b94c1..997b349 100644 --- a/include/linux/tcp.h +++ b/include/linux/tcp.h @@ -315,7 +315,7 @@ struct tcp_sock { */ u32 snd_ssthresh; /* Slow start size threshold */ u32 snd_cwnd; /* Sending congestion window */ - u16 snd_cwnd_cnt; /* Linear increase counter */ + u32 snd_cwnd_cnt; /* Linear increase counter */ u32 snd_cwnd_clamp; /* Do not allow snd_cwnd to grow above this */ u32 snd_cwnd_used; u32 snd_cwnd_stamp; -- 1.5.0.6 k i.
