2020-09-15net/mlx5: remove erroneous fallthroughDan Carpenter
This isn't a fall through because it was after a return statement. The fall through annotation leads to a Smatch warning: drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c:246 mlx5e_ethtool_get_sset_count() warn: ignoring unreachable code.

2020-09-14net: dsa: mt7530: Add the support of MT7531 switchLanden Chao
Add new support for MT7531: MT7531 is the next generation of MT7530. It is also a 7-ports switch with 5 giga embedded phys, 2 cpu ports, and the same MAC logic of MT7530. Cpu port 6 only supports SGMII interface. Cpu port 5 supports either RGMII or SGMII in different HW sku, but cannot be muxed to PHY of port 0/4 like mt7530. Due to SGMII interface support, pll, and pad setting are different from MT7530. This patch adds different initial setting, and SGMII phylink handlers of MT7531. MT7531 SGMII interface can be configured in following mode: - 'SGMII AN mode' with in-band negotiation capability which is compatible with PHY_INTERFACE_MODE_SGMII. - 'SGMII force mode' without in-band negotiation which is compatible with 10B/8B encoding of PHY_INTERFACE_MODE_1000BASEX with fixed full-duplex and fixed pause. - 2.5 times faster clocked 'SGMII force mode' without in-band negotiation which is compatible with 10B/8B encoding of PHY_INTERFACE_MODE_2500BASEX with fixed full-duplex and fixed pause.

2020-09-14mlxsw: spectrum_span: Derive SBIB from maximum port speed & MTUPetr Machata
The SBIB register configures the size of an internal buffer that the Spectrum ASICs use when mirroring traffic on egress. This size should be taken into account when validating that the port headroom buffers are not larger than the chip can handle. Up until now this was not done, which is incidentally not a problem, because the priority group buffers that mlxsw auto-configures are small enough that the boundary condition could not be violated. However when dcbnl_setbuffer is implemented, the user has control over sizes of PG buffers, and they might overshoot the headroom capacity. However the size of the SBIB buffer depends on port speed, and that cannot be vetoed. Therefore SBIB size should be deduced from maximum port speed. Additionally, once the buffers are configured by hand, the user could get into an uncomfortable situation where their MTU change requests get vetoed, because the SBIB does not fit anymore. Therefore derive SBIB size from maximum permissible MTU as well. Remove all the code that adjusted the SBIB size whenever speed or MTU changed.

2020-09-14mlxsw: spectrum: Keep maximum MTU aroundPetr Machata
The maximum port MTU depends on port type. On Spectrum, mlxsw configures all ports as Ethernet ports, and the maximum MTU therefore never changes. Besides checking MTU configuration, maximum MTU will also be handy when setting SBIB, the internal buffer used for traffic mirroring. Therefore, keep it in struct mlxsw_sp_port for easy access.

2020-09-14mlxsw: spectrum_ethtool: Introduce ptys_max_speed callbackPetr Machata
The SBIB register configures the size of an internal buffer that the Spectrum ASICs use when mirroring traffic on egress. This size should be taken into account when validating that the port headroom buffers are not larger than the chip can handle. Up until now this was not done, which is incidentally not a problem, because the priority group buffers that mlxsw auto-configures are small enough that the boundary condition could not be violated. When dcbnl_setbuffer is implemented, the user gets control over sizes of PG buffers, and they might overshoot the headroom capacity. However the size of the SBIB buffer depends on port speed, which cannot be vetoed. There is obviously no way to retroactively push back on requests for overlarge PG buffers, or reject an overlarge MTU, or cancel losslessness of a certain PG. Therefore, instead of taking into account the current speed when calculating SBIB buffer size, take into account the maximum speed that a port with given Ethernet protocol capabilities can have. To that end, add a new ethtool callback, ptys_max_speed, which determines this maximum speed.

However, the only fields of the 32B HW descriptor that is being used by the driver, is also available in the 16B descriptor.

Now it mainly services page_address(), but which accesses struct page only when WANT_PAGE_VIRTUAL or HASHED_PAGE_VIRTUAL is defined otherwise it returns address based on offset, so we prefetch it conditionally.
