[PATCH] net/mlx5/hws: allow HWS support on non esw-manager devices

[Alex Vesker]

On context initialization the reparse capability support
for NIC and FDB tables was required for allowing HWS. This
caused a problem for devices that only want to run NIC
steering. Modified the check to require FDB reparse only
for esw-manager.

[PATCH v2] net/mlx5/hws: fix capability check to allow HWS on non esw-mngr

[Alex Vesker]

On context initialization the reparse capability support
for NIC and FDB tables was required for allowing HWS. This
caused a problem for devices that only want to run NIC
steering and are not the esw-manager fow which  FDB reparse
is disabled. Modified the check to require FDB reparse only for
esw-manager.
