Christophe JAILLET 6dd4b4f393 mlxsw: minimal: Fix an error handling path in 'mlxsw_m_port_create()'
An 'alloc_etherdev()' called is not ballanced by a corresponding
'free_netdev()' call in one error handling path.

Slighly reorder the error handling code to catch the missed case.

Vadim Pasternak 6935af8073 mlxsw: minimal: Add validation for FW version
Add validation for FW version in order to prevent driver initialization
in case FW version is older than expected. FW version validation is
necessary, because use of a new field 'num_of_modules' in MGPIR register
is not backward compatible. FW 'minor' and 'subminor' versions are
expected to be greater than or equal to 2000 and 1886, respectively.

Jiri Pirko 5bcfb6a45a mlxsw: Propagate extack down to register_fib_notifier()
During the devlink reaload the extack is present, so propagate it all
the way down to register_fib_notifier() call in spectrum_router.c.

Vadim Pasternak c100e47caa mlxsw: minimal: Add ethtool support
The minimal driver is chip independent and uses I2C bus for chip access.
Its purpose is to support chassis management on systems equipped with
Mellanox switch ASICs. For example from BMC (Board Management
Controller) device.

Expose a dummy netdev for each front panel port and implement basic
ethtool operations to obtain QSFP/SFP module info through ethtool.
