I should mention that my device is the Vodafone version of ARV4510PW (the
model where the wifi chip is soldered directly on the main board). It has
a few differences from arv4510pw : ethernet switch is different (rtl8306
instead of adm6996) and wifi device correspond to pci 0000:00:0e. On
arv7510pw wifi device is pci 0000:00:0c.
Please also note that i opened another ticket
https://dev.openwrt.org/ticket/21318. You should also apply the patch that
i attached. It's related to irq generated by PCI devices. I think that
without this patch you will not receive irq 66 (USB controller) nor irq
135 (Wifi device).
