Reviewed by:
Submitted by: Update the if_ep driver for the 3C579 and bring over some of the changes from the netbsd driver. This is not complete: the detection of the irq in the eisa does not work and sometimes the reset for the 3C509 in ISA in an EISA bus system don't work ( Need a hard reset to be found again == reset knob).
