This patch tries to ensure that phy interrupt pin won't be asserted after booting. We experienced following issues with current 88E1121R phy init: Marvell 88E1121R phy can be hardware-configured to share MDC/MDIO and interrupt pins for both ports P0 and P1 (e.g. as configured on socrates board). Port 0 interrupt pin will be shared by both ports in such configuration. After booting Linux and configuring eth0 interface, port 0 phy interrupts are enabled. After rebooting without proper eth0 interface shutdown port 0 phy interrupts remain enabled so any change on port 0 (link status, etc.) cause assertion of the interrupt. Now booting Linux and configuring eth1 interface will cause permanent phy interrupt storm as the registered phy 1 interrupt handler doesn't acknowledge phy 0 interrupts. This of course should be fixed in Linux driver too.
