This series provides some low level updates for mlx5 driver needed for both rdma and netdev trees. 1) Termination flow steering table bits and hardware definitions. 2) Introduce the core dump HW access registers definitions. 3) Refactor and cleans-up VF representors functions handlers. 4) Renames host_params bits to function_changed bits and add the support for eswitch functions change event in the eswitch general case. (for both legacy and switchdev modes). 5) Potential error pointer dereference in error handling Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
