* ipq40xx: essedma: Disable TCP segmentation offload for IPv6Sven Eckelmann2020-06-131-7/+4
| | | | | | | | | | | | | | | | | | | | | It was noticed that the the whole MAC can hang when transferring data from one ar40xx port (WAN ports) to the CPU and from the CPU back to another ar40xx port (LAN ports). The CPU was doing only NATing in that process. Usually, the problem first starts with a simple data corruption: $ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.4.0-amd64-netinst.iso -O /dev/null ... Connecting to saimei.ftp.acc.umu.se (saimei.ftp.acc.umu.se)|2001:6b0:19::138|:443... connected. ... Read error at byte 48807936/352321536 (Decryption has failed.). Retrying. But after a short while, the whole MAC will stop to react. No traffic can be transported anymore from the CPU port from/to the AR40xx PHY/switch and the MAC has to be resetted.

* ipq40xx: 5.4: fix ethernet driverRobert Marko2020-03-161-29/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 5.4 kernel old u32 array way of setting network features was dropped and linkmode is now the only way. So lets migrate the EDMA driver to support linkmode. Also, old get/set settings API for ethtool is also dropped so lets convert to new ksettings API while at it as it demands linkmode. Now, gigabit works properly as well as ethtool. Previously you would get this in ethtool: root@OpenWrt:/# ethtool eth1 Settings for eth1: Supports Wake-on: d Wake-on: d Current message level: 0x00000000 (0) Link detected: yes Now, features are properly advertised: root@OpenWrt:/# ethtool eth1 Settings for eth1: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/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/Half 1000baseT/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 Signed-off-by: Robert Marko <robert.marko@sartura.hr>
* ipq40xx: 5.4: fix of_get_mac_address obsolete usage OOPsPetr Štetiar2020-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_get_mac_address returns valid pointer or ERR_PTR since 5.2 via commit d01f449c008a ("of_net: add NVMEM support to of_get_mac_address") so the patch fixes following OOPs on nbg6617: Unable to handle kernel paging request at virtual address ffffffed CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.4.24 #0 PC is at edma_axi_probe+0x444/0x1114 LR is at bus_find_device+0x88/0x9c Where the PC can be resolved to: >>> l *edma_axi_probe+0x444 0xc067be5c is in edma_axi_probe (./include/linux/string.h:378). >>> l *edma_axi_probe+0x43f 0xc067be57 is in edma_axi_probe (drivers/net/ethernet/qualcomm/essedma/edma_axi.c:936) Which leads to the following code fragment: 935 mac_addr = of_get_mac_address(pnp); 936 if (mac_addr) 937 memcpy(edma_netdev[idx_mac]->dev_addr, mac_addr, ETH_ALEN); Where using mac_addr=0xffffffed (-ENODEV) as source address in memcpy() is causing the OOPs.
