    net/mlx4_core: Add Crdump FW snapshot support · bedc989b
    Alex Vesker authored Jul 12, 2018
    
    
    Crdump allows the driver to create a snapshot of the FW PCI
    crspace and health buffer during a critical FW issue.
    In case of a FW command timeout, FW getting stuck or a non zero
    value on the catastrophic buffer, a snapshot will be taken.
    
    The snapshot is exposed using devlink, cr-space, fw-health
    address regions are registered on init and snapshots are attached
    once a new snapshot is collected by the driver.
