I intend to open a bug report on this, but first wanted to pester
people for advice, in case I'm being silly.
On our LAN, we have several boxes, including several versions of
FreeBSD. I'm upgrading our internal switch to some Cisco hardware.
Upon migrating our cables over however, we have two FreeBSD boxes,
running 4.x, with varieties of the Macronix 98715 chipset.

------------------
Both of these boxes work fine with our FlowPoint DSL router, a
cheesy 3Com 10bT hub, and an even cheesier Ark Technologies
autosensing switch.
I'm installing a Cisco Catalyst 2924 XL running IOS Version
11.2(8)SA3.
The symptoms:
machine 'one':
Upon reboot, both the switch and the NIC would report a link,
but as soon as the OS initialized the card, both the switch and
NIC would stop reporting a link. 'ifconfig' would reveal
'autosense: no carrier' (typed from memory, so perhaps not an
exact quote).
machine 'two':
Both the NIC and the switch would report a link, but no traffic
(pinging, etc.) would come though. (I did not attempt a tcpdump.)
I only see one Macronix-related error reported (kern/17728), but
the PR doesn't have any real info.
Has anyone else seen problems like this with these NICs?
