The APIs can be used by Ethernet drivers without actually loading a PHY driver. This may become more widespread in the future with 802.3z compatible MAC PCS devices being locally driven by the MAC driver when configuring for a PHY mode with in-band negotiation. Check that drv is not NULL before reading from it. Signed-off-by:

For some reason, PHYLINK does not put the copper modes for 802.3bz (NBASE-T) and 802.3an-2006 (10GBASE-T) in the PHY's supported mask, when the PHY-MAC connection is a 10G-capable one (10GBase-KR, 10GBase-R, USXGMII). One possible way through which the cable side can work at the lower speed is by having the PHY emit PAUSE frames towards the MAC. So fix that omission. Also include the 2500Base-X fiber mode in this list while we're at it. Signed-off-by:

snps databook noted that physical coding sublayer (PCS) interface that can be used when the MAC is configured for the TBI, RTBI, or SGMII PHY interface. we have RGMII and SGMII in a SoC and it also has the PCS block. it needs stmmac_init_phy and stmmac_mdio_register function for initializing phy when it used RGMII interface.

Ido Schimmel says: ==================== mlxsw: Add tunnel devlink-trap support This patch set from Amit adds support in mlxsw for tunnel traps and a few additional layer 3 traps that can report drops and exceptions via devlink-trap. These traps allow the user to more quickly diagnose problems relating to tunnel decapsulation errors, such as packet being too short to decapsulate or a packet containing wrong GRE key in its GRE header. Patch set overview: Patches #1-#4 add three additional layer 3 traps. Two of which are mlxsw-specific as they relate to hardware-specific errors. The patches include documentation of each trap and selftests. Patches #5-#8 are preparations. They ensure that the correct ECN bits are set in the outer header during IPinIP encapsulation and that packets with an invalid ECN combination in underlay and overlay are trapped to the kernel and not decapsulated in hardware. Patches #9-#15 add support for two tunnel related traps. Each trap is documented and selftested using both VXLAN and IPinIP tunnels, if applicable. ==================== Signed-off-by: -

Initialize ECN mapping registers during router init according to INET_ECN_encapsulate() and INET_ECN_decapsulate(). For IP-in-IP encapsulation, this is required to ensure that ECN bits in the underlay are set in accordance with the kernel. For decapsulation, this is required to ensure that packets with invalid ECN combination in underlay and overlay are trapped to the kernel and not forwarded. Signed-off-by:

Saeed Mahameed says: ==================== Mellanox, mlx5 E-Switch chains and prios This series has two parts, 1) A merge commit with mlx5-next branch that include updates for mlx5 HW layouts needed for this and upcoming submissions. 2) From Paul, Increase the number of chains and prios Currently the Mellanox driver supports offloading tc rules that are defined on the first 4 chains and the first 16 priorities. The restriction stems from the firmware flow level enforcement requiring a flow table of a certain level to point to a flow table of a higher level. This limitation may be ignored by setting the ignore_flow_level bit when creating flow table entries. Use unmanaged tables and ignore flow level to create more tables than declared by fs_core steering. Manually manage the connections between the tables themselves. HW table is instantiated for every tc <chain,prio> tuple. The miss rule of every table either jumps to the next <chain,prio> table, or continues to slow_fdb. This logic is realized by following this sequence: 1. Create an auto-grouped flow table for the specified priority with reserved entries Reserved entries are allocated at the end of the flow table. Flow groups are evaluated in sequence and therefore it is guaranteed that the flow group defined on the last FTEs will be the last to evaluate. Define a "match all" flow group on the reserved entries, providing the platform to add table miss actions. 2. Set the miss rule action to jump to the next <chain,prio> table or the slow_fdb. 3. Link the previous priority table to point to the new table by updating its miss rule. Please pull and let me know if there's any problem. ==================== Signed-off-by: -

T6 can support 2 egress traffic management channels per port to double the total number of traffic classes that can be configured. In this configuration, if the class belongs to the other channel, then all the queues must be bound again explicitly to the new class, for the rate limit parameters on the other channel to take effect. So, always explicitly bind all queues to the port rate limit traffic class, regardless of the traffic management channel that it belongs to. Also, only bind queues to port rate limit traffic class, if all the queues don't already belong to an existing different traffic class.

Vladimir Oltean says: ==================== Rate adaptation for Felix DSA switch When operating the MAC at 2.5Gbps (2500Base-X and USXGMII/QSXGMII) and in combination with certain PHYs, it is possible that the copper side may operate at lower link speeds. In this case, it is the PHY who has a MAC inside of it that emits pause frames towards the switch's MAC, telling it to slow down so that the transmission is lossless. These patches are the support needed for the switch side of things to work. ==================== Signed-off-by: -
Alex Marginean authored
If the serdes link is set to 2500 using interfce type 2500base-X, lower link speeds over on the line side should still be supported. Rate adaptation is done out of band, in our case using AQR PHYs this is done using flow control. Signed-off-by:
-
Alex Marginean authored
Flow control is used with 2500Base-X and AQR PHYs to do rate adaptation between line side 100/1000 links and MAC running at 2.5G. This is independent of the flow control configuration settled on line side though AN. In general, allowing the MAC to handle flow control even if not negotiated with the link partner should not be a problem, so the patch just enables it in all cases. Signed-off-by:
