Nikolay Aleksandrov 26ba30221c devlink: add generic device max_sfs parameter
Add a new generic devlink device parameter (max_sfs) to control if and
how many light-weight NIC subfunctions can be created. Subfunctions are
a light-weight network functions backed by an underlying PCI function.
Their lifecycle can already be managed by devlink, but currently users
cannot enable them in the device. They can be enabled/disabled only via
external vendor tools. This parameter allows subfunctions to be enabled
(>0) or disabled (0) via devlink. A subsequent patch will add support
for max_sfs to the mlx5 driver.
