cvs diff: if_fec.c interrupt handling fix
The phy_read() function can return bad values if interrupts occurs during
reading a PHY register.
During interrupt handling the iEvent_MII bit is incorrectly cleared. That bit
is polled in phy_read() and phy_write() functions and should not be cleared in
the interrupt handler.
