Merge branch 'mlxsw-Add-support-for-new-port-types-and-speeds-for-Spectrum-2'
Ido Schimmel says: ==================== mlxsw: Add support for new port types and speeds for Spectrum-2 Shalom says: This patchset adds support for new port types and speeds for Spectrum-2. Patch kernel-patches#1 + kernel-patches#2 removes an unsupported PTYS field and a duplicate link mode entry. Patch kernel-patches#3 queries port's connector type from firmware instead of deriving it from port admin state. Patch kernel-patches#4 renames functions which relate to port type-speed to be Spectrum-1 specific. Patch kernel-patches#5 defines port type-speed operations and applies it for Spectrum-1. Patch kernel-patches#6 + kernel-patches#7 are small renaming and cosmetic changes. Patch kernel-patches#8 adds new port type-speed fields for PTYS register. These new fields extend the existing ones in order to support more types and speeds. Patch kernel-patches#9 adds Spectrum-2 support for port type-speed operations. Patch kernel-patches#10 adds Spectrum-2 new port types and speeds. For Spectrum-2, the user must configure all the types per speed if he / she wants a specific speed to be advertised. For example, if the user wants to advertise 100Gbps 4-lanes speed, the following ethtool bits should be advertised: Supported ethtool bits for 100Gbps 4-lanes: 0x1000000000 100000baseKR4 Full 0x2000000000 100000baseSR4 Full 0x4000000000 100000baseCR4 Full 0x8000000000 100000baseLR4_ER4 Full Command for advertising 100Gbps 4-lanes: ethtool -s enp3s0np1 advertise 0xF000000000 ==================== Signed-off-by: David S. Miller <[email protected]>
