[dpdk-dev] [PATCH v2 0/3] Add link status notification support to Mellanox PMDs

[Adrien Mazarguil <adrien.mazarguil@6wind.com>]

Mellanox PMDs (mlx4 and mlx5) support link status notification with
libibverbs through a file descriptor, in a manner reminiscent of UIO/VFIO.

It still requires a new "external" interrupt handler type since contrary
to other types, this file descriptor must not be processed by EAL.

Changes in v2:
- Only changes caused by rebase on v2 of previous patchsets
  ("Mellanox ConnectX-4 PMD (mlx5)" and
  "Enhance mlx5 with Mellanox OFED 3.1")

Nelio Laranjeiro (3):
  eal: new interrupt handler type
  mlx4: handle interrupts
  mlx5: handle interrupts
