2025-01-15net: phylink: pass neg_mode into c22 state decoderRussell King (Oracle)
Pass the current neg_mode into phylink_mii_c22_pcs_get_state() and phylink_mii_c22_pcs_decode_state(). Update all users of phylink PCS that use these functions.

2023-05-18net: lan966x: Add support for DSCP rewriteHoratiu Vultur
Add support for DSCP rewrite in lan966x driver. On egress DSCP is rewritten from either classified DSCP, or frame DSCP. Classified DSCP is determined by the Analyzer Classifier on ingress, and is mapped from classified QoS class and DP level. Classification of DSCP is by default enabled for all ports. It is required that DSCP is trusted for the egress port *and* rewrite table is not empty, in order to rewrite DSCP based on classified DSCP, otherwise DSCP is always rewritten from frame DSCP.

Add support for rewrite of PCP and DEI value, based on QoS and DP level. The DCB rewrite table is queried for mappings between priority and PCP/DEI. The classified DP level is then encoded in the DEI bit, if a mapping for DEI exists.

2022-12-22net: lan966x: Fix configuration of the PCSHoratiu Vultur
When the PCS was taken out of reset, we were changing by mistake also the speed to 100 Mbit. But in case the link was going down, the link up routine was setting correctly the link speed. If the link was not getting down then the speed was forced to run at 100 even if the speed was something else. On lan966x, to set the speed link to 1G or 2.5G a value of 1 needs to be written in DEV_CLOCK_CFG_LINK_SPEED. This is similar to the procedure in lan966x_port_init. The issue was reproduced using 1000base-x sfp module using the commands: ip link set dev eth2 up ip link addr add 10.97.10.2/24 dev eth2 ethtool -s eth2 speed 1000 autoneg off Fixes: d28d6d2e37d1 ("net: lan966x: add port module support") Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Reviewed-by: Piotr Raczynski <piotr.raczynski@intel.com> Link: https://lore.kernel.org/r/20221221093315.939133-1-horatiu.vultur@microchip.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2022-08-22net: lan966x: Add QUSGMII support for lan966xMaxime Chevallier
The Lan996x controller supports the QUSGMII mode, which is very similar to QSGMII in the way it's configured and the autonegociation capababilities it provides. This commit adds support for that mode, treating it most of the time like QSGMII, making sure that we do configure the PCS how we should.

2022-04-11net: lan966x: Add FDMA functionalityHoratiu Vultur
Ethernet frames can be extracted or injected to or from the device's DDR memory. There is one channel for injection and one channel for extraction. Each of these channels contain a linked list of DCBs which contains DB. The DCB contains only 1 DB for both the injection and extraction. Each DB contains a frame. Every time when a frame is received or transmitted an interrupt is generated. It is not possible to use both the FDMA and the manual injection/extraction of the frames. Therefore the FDMA has priority over the manual because of better performance values.

2021-12-13net: lan966x: Fix the configuration of the pcsHoratiu Vultur
When inserting a SFP that runs at 2.5G, then the Serdes was still configured to run at 1G. Because the config->speed was 0, and then the speed of the serdes was not configured at all, it was using the default value which is 1G. This patch stop calling the serdes function set_speed and allow the serdes to figure out the speed based on the interface type.
