Bug description
Some Ubiquiti loco xw have a hardware bug which results in an interface shutdown with now possibility to bring the interface without reboot. More details, see https://dev.openwrt.org/ticket/19085
Steps for building workaround
Find a way to detect hang of eth0
In general there are two places where uid of PHY is printed.
1. ag71xx_phy.c
function: static int ag71xx_phy_connect_multi(struct ag71xx *ag)
....
DBG("%s: PHY found at %s, uid=%08x\n",
dev_name(dev),
dev_name(&ag->mii_bus->phy_map[phy_addr]->dev),
ag->mii_bus->phy_map[phy_addr]->phy_id);
dev_info(dev, "connected to PHY at %s [uid=%08x, driver=%s]\n",
dev_name(&phydev->dev), phydev->phy_id, phydev->drv->name);
2. ag71xx_main.c
void ag71xx_link_adjust(struct ag71xx *ag)
....
struct device *dev = &ag->pdev->dev;
struct ag71xx_platform_data *pdata = ag71xx_get_pdata(ag);
struct phy_device *phydev = NULL;
int phy_addr;
int ret = 0;
for (phy_addr = 0; phy_addr < PHY_MAX_ADDR; phy_addr++) {
if (!(pdata->phy_mask & (1 << phy_addr)))
continue;
if (ag->mii_bus->phy_map[phy_addr] == NULL)
continue;
DBG("%s: PHY found at %s, uid=%08x\n",
dev_name(dev),
dev_name(&ag->mii_bus->phy_map[phy_addr]->dev),
ag->mii_bus->phy_map[phy_addr]->phy_id);
if (phydev == NULL)
phydev = ag->mii_bus->phy_map[phy_addr];
}
dev_info(dev, "connected to PHY at %s [uid=%08x, driver=%s]\n",
dev_name(&phydev->dev), phydev->phy_id, phydev->drv->name);
Detection in ag71xx_link_adjust() in file ag71xx_main.c ist possible. See http://pastebin.com/0ze9iFcb for an example.
