ipv4: make tcp_notsent_lowat sysctl knob behave as true unsigned int

> cat /proc/sys/net/ipv4/tcp_notsent_lowat -1 > echo 4294967295 > /proc/sys/net/ipv4/tcp_notsent_lowat -bash: echo: write error: Invalid argument > echo -2147483648 > /proc/sys/net/ipv4/tcp_notsent_lowat > cat /proc/sys/net/ipv4/tcp_notsent_lowat -2147483648 but in documentation we have "tcp_notsent_lowat - UNSIGNED INTEGER" v2: simplify to just proc_douintvec Signed-off-by: Pavel Tikhomirov <[email protected]> Signed-off-by: David S.
