Actually I don't think the extra struct sock field is needed. The patch
looks right in its own way but Im sure it ought to use the current route
for the socket to get the irtt - so that if the socket switches route
eg from ethernet to ax.25 the initial rtt and reset estimate is used.

The 2.1.x tcp has also changed a lot so Im not sure if the patch is
relevant to it. I'll file it to check one day
