>Description:
On a lenovo T61 without any Ethernet cable plugged in, wm0 reports device
timeouts approximately every 30 minutes.

dmesg | grep wm0:
wm0 at pci0 dev 25 function 0: Intel i82801H (M_AMT) LAN Controller, rev. 3
wm0: interrupting at ioapic0 pin 20
wm0: PCI-Express bus
wm0: FLASH
wm0: Ethernet address 00:1f:e2:14:b6:41
igphy0 at wm0 phy 1: i82566 10/100/1000 media interface, rev. 0
wm0: device timeout (txfree 4095 txsfree 63 txnext 52)

The messages from today were at 7:32, 7:57, 8:29, 9:07, 9:35, 10:13,
10:42, 11:15, 11:47, 12:17, 12:52, 13:24.

This also happens when a cable is plugged in, general network connectivity
seems to work fine nevertheless.

 I get such timeouts when samba is running and no cable is plugged in, but
 the timeouts only happens ever 6 hours.
 Stopping samba also stopped these messages.

 Hm, I have dhclient running, perhaps that's the cause.

 When I stop dhclient, the messages stop.

 Scapy's command to reproduce the bug quickly:

 >> sendp(Ether(dst="ff:ff:ff:ff:ff:ff")/IP(src="0.0.0.0",dst="255.255.255.255")/UDP(sport=68,dport=67)/BOOTP(chaddr="00:30:48:xx:yy:zz")/DHCP(options=[("message-type","discover"),"end"]), iface="wm0")

 Do above command more than 47 times.

 I can't understand why it occurs. Please debug!

 Hi,

 until yesterday I never had any troubles with my "Intel i82801H (AMT)
 LAN Controller" aka wm0.  I didn't upgrade netbsd-6 since BETA2 and my
 usage pattern didn't change too.  Yesterday, during the rehash of a
 rather large file over nfs..

    [ netbsd-6; nfs3 ] <--- Ethernet ---> [ linux; nfs3; rtorrent]

 ..lots of wm0 timeouts rendered the box unreachable.  Now I'm not sure
 if there was some interaction between wm0 and dhcpcd but I'm sure that
 I've been rehashing large files before (which always pulls a continuous
 stream of about 40-50MB/s through the cable).

 Here are the messages (probably related to kern/40981):

 Now, I've seen these timeouts before but until now, they never had any
 negative effect (or maybe I just didn't notice)..

 Thanks,

Date: Fri, 5 Nov 2021 05:52:50 +0000

 Module Name:	src
 Committed By:	msaitoh
 Date:		Fri Nov  5 05:52:49 UTC 2021

 Modified Files:
 	src/sys/dev/pci: if_wm.c

 Log Message:
 Fix a bug that device timeout still happens on ICH/PCH. Fixes PR kern/56478.

  - if_wm.c rev. 1.695 for PR kern/40981 still had a problem. The workaround
    flag was unexpectedly cleared when a cable is not connected, SIOCINITIFADDR
    was called, or if_init was called. Fix it.
  - Add debug printf()s.
