[win-pv-devel] [PATCH xenvif 0/8] Fix TCP throughput performance regressions

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

It has become apparent in recent testing that the master branch has
suffered significant TCP throughput performance regressions when compared
to the stable branches. This series fixes various issues that have caused
this regression.

Paul Durrant (8):
  Revert reversion of "Deferring transmit completion causes...
  Revert "Replace uses of MmAllocatePagesForMdlEx in __AllocatePage"
  Revert complete poller subsystem
  Remove KTIMERS from transmit and receive paths (again)
  Re-instate 264bde12 "Introduce a threaded DPC into the receiver code"
  Get rid of the 'Retry' exit from the ring poll routines
  Don't force event channel unmasking
  Set packet transmit completion information outside of ring lock
