A high number of MAD packet drops are observed in the mlx4 MAD proxy
system. These are fixed by separating the parameters for the tunnel
vs. wire QPs and by introducing a separate worker-thread for the wire
QPs.

Support for MRA and REJ with its reason being timeout is also added.

Dynamic debug prints adjusted and amended.

HÃ¥kon Bugge (5):
  IB/mlx4: Add and improve logging
  IB/mlx4: Add support for MRA
  IB/mlx4: Separate tunnel and wire bufs parameters
  IB/mlx4: Fix starvation in paravirt mux/demux
  IB/mlx4: Add support for REJ due to timeout
