  net/mlx5: Protect against infinite recovery requests (2019-01-10 12:11:31 +0200)

----------------------------------------------------------------
mlx5e-updates-2019-01-10 (mlx5 SW reset)

This series from Feras and Alex, adds the support for mlx5 software reset

Some fatal hardware errors are recoverable by issuing software reset.
Since mlx5 is a function per port, to avoid extra reset by the 2nd
function driver instance, we add a vendor specific access gateway (VSC)
to synchronize software resets between the different pcie functions of
the same HCA.

Before a software reset is issued we want to capture a Crdump FW snapshot,
this is done via the existing devlink region snapshot API, a user can
read this crdump later on demand.

The new mlx5 devlink region snapshot support is documented under
Documentation/networking/mlx5.rst
