System: NetBSD p84ce2e 1.3 NetBSD 1.3 (MINT) #88: Sun Feb 22 22:28:36 JST 1998 kei@localhost:/current/work/sys/arch/mac68k/compile/MINT mac68k

>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.

State-Changed-Why:  
Please confirm whether you still have the hardware available to test any 
changes made for this card.  I'd like to resolve it, but it will take some 
help from someone with an Etherport SE/30, of course. 

Thanks.

State-Changed-Why:  
Keiki Sunagawa replied that he no longer has access to the hardware,
however, he might get this hardware again sometime in the future
(or someone else might), so let's suspend, rather than close, this
PR, pending a new opportunity to properly handle the reported
problem.

State-Changed-Why:
Submitter cannot test, but someone else might be able to. Such bugs should be
open, not suspended, unless/until we get a special PR state for them;
suspended is for bugs where nothing at all can be done for the time being.
