FS#2349 - gl-ar150 lan port always up when using ath79 & 19.07 (ar71xx ok) #6090

Hello Team

Testing using OpenWrt 19.07-SNAPSHOT r10233-4a7a8d93fa, ath79 image, connected via wifi

removing both eth0 & eth1 from their interface, rebooting, then doing

ip l set up eth0

ip l set up eth1

eth0 (lan port) is always up even if no cables are connected (state UP, no NO-CARRIER) 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 link/ether e4:95:6e:45:32:f8 brd ff:ff:ff:ff:ff:ff 3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000 link/ether e4:95:6e:45:32:f8 brd ff:ff:ff:ff:ff:ff

I would say it's a know bug because the led is configured to look at the switch and not the interface ar71xx images are working ok

here part of the dmesg for ath79 [ 0.745353] ag71xx 19000000.eth: Could not connect to PHY device. Deferring probe. [ 1.480124] ag71xx 1a000000.eth: connected to PHY at fixed-0:00 [uid=00000000, driver=Generic PHY] [ 1.488671] eth0: Atheros AG71xx at 0xba000000, irq 5, mode: gmii [ 1.865945] ag71xx 19000000.eth: connected to PHY at mdio-bus.0:1f:04 [uid=004dd041, driver=Generic PHY] [ 1.875354] eth1: Atheros AG71xx at 0xb9000000, irq 4, mode: mii

and for ar71xx [ 1.571027] eth0: Atheros AG71xx at 0xb9000000, irq 4, mode:MII [ 2.244049] eth1: Atheros AG71xx at 0xba000000, irq 5, mode:GMII

the 2 ports are switched between ar71xx and ath79 images

I've tried to randomly change the dts, but I have no idea what I'm doing ...

The relevant definition is found here: https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/generic/base-files/etc/board.d/01_leds#L93-L95

Typically, one of the ports has to be set up with the netdev and one with the switch. But I never remember which one ... Despite, it would be possible that the 0x02 is wrong. But essentially, all you need to change should be those two lines.
