* ipq40xx: net: ethernet: edma: use generic ksettings functionsRobert Marko2020-12-231-56/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we now have a proper PHY driver for QCA807x and AR803x has already been supported properly there is no need for the driver to be poking on PHY registers for ethtool ops. So, lets simply use the generic phy_ethtool_ksettings_get/phy_ethtool_ksettings_set functions. This also has the advantage of properly populating stuff other than speeds like, transceiver type, MDI-X etc. ethtool before: root@OpenWrt:/# ethtool eth1 Settings for eth1: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full 1000baseX/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full 1000baseX/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: No Link partner advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 4 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000000 (0) Link detected: yes ethtool after: root@OpenWrt:/# ethtool eth1 Settings for eth1: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full 1000baseX/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full 1000baseX/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Link partner advertised pause frame use: Symmetric Receive-only Link partner advertised auto-negotiation: Yes Link partner advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 4 Transceiver: external Auto-negotiation: on MDI-X: off (auto) Supports Wake-on: d Wake-on: d Current message level: 0x00000000 (0) Link detected: yes Signed-off-by: Robert Marko <robert.marko@sartura.hr>
* ipq40xx: net: ethernet: edma: fix link detectionRobert Marko2020-12-231-0/+4
| | | | | | | PHY needs to be soft reset before starting it from ethernet driver as AR40xx calibration will leave it in unwanted state. Signed-off-by: Robert Marko <robert.marko@sartura.hr>
* ipq40xx: edma: convert to of_mdio_find_bus()Robert Marko2020-12-231-21/+4
| | | | | | | | | | | | | | With the reworked MDIO driver, EDMA will fail to get the MII BUS as it used the MII BUS stored inside the MDIO structure private data. This obviously does not work with the modernized driver, so lets switch to using a purpose build of_mdio_find_bus() which will return the MII BUS and only requires the MDIO node to be passed. This is easy as we already have the node parsed. Also, since we now require OF_MDIO add that as dependency. Signed-off-by: Robert Marko <robert.marko@sartura.hr>
* ipq40xx: revert usage of VLAN S-TAGDavid Bauer2020-12-141-14/+5
| | | | | | | | | | | This reverts the usage of the S-Tag for separating LAN and WAN port on the embedded switch. Many users complained about not being able to manage C-Tag addition / removal on the switch as well as degraded performance. Fixes: commit 9da2b567605b ("ipq40xx: fix ethernet vlan double tagging") Signed-off-by: David Bauer <mail@david-bauer.net>
* ipq40xx: enable RX hash / CTAG TX offloading for single-phyDavid Bauer2020-11-011-0/+9
| | | | | | | | | | | | This re-enables offloading features disabled by commit 9da2b567605b ("ipq40xx: fix ethernet vlan double tagging"). Single-PHY devices use port-based VLANs on the switch, therefore no S-TAG magic is involved here. Re-enabling these features restores throughput back to 950 Mbit/s.

* ipq40xx: remove support for kernel 4.19Adrian Schmutzler2020-10-196-0/+4769
The target uses 5.4 as default kernel since 03/2020. Kernel 4.19 support is not really maintained anymore, it does not seem to be needed, and removing it will make upcoming driver updates easier. Thus, remove it. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
