It's connected to a Cisco 2924 VLAN switch, and both the switch port and
the wm0 device on the laptop are explicitly configured for 100/full.

Yes, and yes.  When I manually configure it for an address on the VLAN
that's actually on that port, and try to ping a neighbor, I can see this
(using tcpdump on the neighbor):

13:24:21.596308 ARP, Request who-has hamartun-gw.hamartun.priv.no tell 172.27.202.50, length 46
13:24:21.596326 ARP, Reply hamartun-gw.hamartun.priv.no is-at 00:13:72:f7:00:06 (oui Unknown), length 28

However, the ARP response is never received, so it just keeps trying.

That's just the host itself answering, right?  If I do this on the
(working) iwn0 WiFi interface, I get more responses, with much longer
RTTs, and "(DUP!)" messages.  I assume that's neighbours answering?
