tcp: collapse more than two on retransmission
I always had thought that collapsing up to two at a time was
intentional decision to avoid excessive processing if 1 byte
sized skbs are to be combined for a full mtu, and consecutive
retransmissions would make the size of the retransmittee
double each round anyway, but some recent discussion made me
to understand that was not the case. Thus make collapse work

The only trick here is that a socket of a given type (TCP ipv4,

must use different 'nulls' end-of-chain values for two tables.
We define a large value :
