[TCP]: TCP Compound quad root function
The original code did a 64 bit divide directly, which won't work on 32 bit platforms. Rather than doing a 64 bit square root twice, just implement a 4th root function in one pass using Newton's method. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.
