>Description:
	EtherPort IIN has 8-bit bus and its ByteLanes is E1. So, the last
	nibble of the offset address for accessing it should be [048c].
>How-To-Repeat:
	With EtherPort IIN, do 'ifconfig.'  It doesn't occur on EtherPort
	SE/30.
>Fix:

	Unfortunately, the following patch only solves the hang problem.
	In other words, it doesn't work properly.

	Ken Nakata said to me this change might not break the EtherPort SE/30.
