This patch replaces existing min_tso_segs() with tso_segs() CC callbak for CC algorithm to provides explicit tso segment number of each data burst and overrides tcp_tso_autosize(). No functional change.
Eric, Neal, looks good? The min rtt thing in tcp_tso_autosize() helps a bit but if the sender gets congested for a longer stretch min_rtts on new connections are high and we're back to sending small TSO, keeping the sender overloaded. Which is to say - I _hope_ this also solves some of Meta's problems :)
