At $(U_BOOT)/drivers/net/bcm570x.c files header, it says * Broadcom BCM570x Ethernet Driver for U-Boot. * Support 5701, 5702, 5703, and 5704. Single instance driver. --> Single Instance Driver. Does this mean it doesn't handle Interrupt. Sorry I cannot say more as I don't have any knowledge abt this Also, CONFIG_BCM570x is used in $(U_BOOT)/include/configs/BMW.h which is a MPC based Board. May be MPC uses interrupts for its operation inside U-Boot.
