[TCP]: Make snd_cwnd_cnt 32-bit
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 <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.
