natsemi.c failure in 2.4.6

["Daniel A. Nobuto" <ramune@bigfoot.com>]

Hi all,

	Found that in 2.4.6, Natsetmi card I have doesn't receive
traffic anymore.  It worked in 2.4.5, though.

	The natsemi card is forced to 10/half via mii-diag at boot,
and given a different MAC address (due to some problems I had with
the original MAC address and netbooting a sparc).  Forcing it to
100/full didn't work, either.

	A continuous ping from the Linux box to another system on the
LAN showed only outbound traffic in tcpdump, but the recieving end
(an SS4 running NetBSD) showed both incoming and outgoing packets
(i.e. icmp echo and echo-reply).

	Any ideas on how I can get about tracking the problem down?

	Thanks,

-- DN

going on, either.):
