The following changes fix a potential DoS by peers or local users on
network interfaces using the sfc driver (and possibly others) with TSO
enabled (as it is by default).

Please apply patches 1 and 2 to the net tree and your stable update
queue.  I'm not sure whether patch 3 is really important.

Ben.

Ben Hutchings (3):
  net: Allow driver to limit number of GSO segments per skb
  sfc: Fix maximum number of TSO segments and minimum TX queue size
  tcp: Apply device TSO segment limit earlier
Series applied, thanks Ben.  I think patch #3 does matter, because
anything in TCP that cares about the "limit" now must make both
tests.
