   stack TCP connections.

 - fixes for i386 / x86-64 structure padding differences (ABI
   compatibility for 32-on-64) from Yann Droneaud.

 - a pile of SRP initiator fixes from Bart Van Assche.

 - fixes for a writeback / memory allocation deadlock with NFS over
   IPoIB connected mode from Jiri Kosina.

 - the usual fixes and cleanups to mlx4, mlx5, cxgb4 and other low-level
   drivers.
