I also have another hardware with two ethernet interfaces and two independant PHYs. But the two PHYs are wired to the same interrupt. This is working perfectly up to Linux 3.12. But since your commit, introduced in Linux 3.13, my interfaces don't work anymore as the second PHYs can't register IRQ. Reading the commit log, I can't really understand the reason for the change. Is it really worth it, and therefore how shall my case be handled ? Christophe
