#9042 closed defect (fixed)

IP17xx Ethernet switch functionality is broken after r25720 (Atheros trunk)

Reported by: johnc60@… Owned by: developers
Priority: high Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: IP17xx, switch, Atheros Cc:

Description

On an Airlink101 AR430W, as of version r25720 on the Atheros trunk, the IP17xx five-port Ethernet switch is no longer recognized. The usual router configuration of assigning switch ports 0-3 to the LAN and port 4 to the WAN will no longer work. The DLink DIR-300 and other similar hardware with an IP17xx switch is most likely broken also.

The Atheros snapshot is OK because it is at version r25704. Any build against version r25720 and higher is broken.

The log from r25720 (and higher) shows that the switch is not being detected and eth0 is being configured as "Generic PHY". Therefore swconfig does not see a switch on eth0 anymore.
root@OpenWrt:/# dmesg

<snip>

eth0: Atheros AR231x: 00:1d:6a:dc:f8:08, irq 4
ar231x_eth_mii: probed
eth0: attached PHY driver [Generic PHY] (mii_bus:phy_addr=0:00)

<snip>

root@OpenWrt:/# swconfig dev eth0 show
Failed to connect to the switch

The log from the older r25719 shows that the switch is properly recognized and eth0 is configured as "IC+ IP17xx".
