2019-10-06mlxsw: minimal: Add validation for FW versionVadim Pasternak
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.

2019-10-04mlxsw: Propagate extack down to register_fib_notifier()Jiri Pirko
During the devlink reaload the extack is present, so propagate it all the way down to register_fib_notifier() call in spectrum_router.c. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-04mlxsw: Register port netdevices into net of coreJiri Pirko
When creating netdevices for ports, put them under network namespace that the core/parent devlink belongs to. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-05-30mlxsw: i2c: Extend initialization with querying firmware infoVadim Pasternak
Extend initialization flow with query request for firmware info in order to obtain firmware version info. This info is to be provided to minimal driver to support ethtool get_drvinfo() interface.

2019-04-04mlxsw: Remove ndo_get_port_parent_id implementationJiri Pirko
Remove implementation of get_port_parent_id ndo and rely on core calling into devlink for the information directly. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-04mlxsw: Pass switch ID through devlink_port_attrs_set()Jiri Pirko
Pass the switch ID down the to devlink through devlink_port_attrs_set() so it can be used by devlink_compat_switch_id_get(). Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-28mlxsw: Remove ndo_get_phys_port_name implementationJiri Pirko
Rely on the previously introduced fallback and let the core call devlink directly in order to get the physical port name. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-28mlxsw: Implement ndo_get_devlink_portJiri Pirko
In order for devlink compat functions to work, implement ndo_get_devlink_port. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-24mlxsw: Move devlink_port_attrs_set() call before registerJiri Pirko
Since attrs are static during the existence of devlink port, set the before registration of the port. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-12mlxsw: minimal: Initialize base_macJiri Pirko
Currently base_mac is not initialized which causes wrong reporting of zeroed parent_id to userspace. Fix this by initializing base_mac properly.

2019-03-03mlxsw: minimal: Add ethtool supportVadim Pasternak
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.
