Title:
  xfrm4_gc_thresh should default to INT_MAX

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The default xfrm4_gc_thresh (and xfrm6_gc_thresh) value is currently
  32k, but in systems with > 16 cpus, this will (eventually) cause
  failures when ipsec uses too many dst objects.  As xfrm doesn't
  actually manage its dst objects, the flowcache does, this parameter
  doesn't actually control xfrm dst gc, it only causes failures when
  exceeded.  Thus is should simply be set to INT_MAX.

  Upstream commit that fixes this is
