Hi
I tried this on head ( 7.0-CURRENT #0: Tue Dec 27 19:37:10 CET 2005 )
Take dc out of the kernel config file and only make it as a module.
on cosole 1:
ddev# kldload if_dc
dc0: <Macronix 98715AEC-C 10/100BaseTX> port 0xd400-0xd4ff mem
0xe6901000-0xe69010ff irq 5 at device 13.0 on pci0
dc0: Ethernet address: 00:80:c6:f9:fa:f5
miibus1: <MII bus> on dc0
ukphy0: <Generic IEEE 802.3u media interface> on miibus1
ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 100baseT4
on console 2:
ddev# tcpdump -i dc0
tcpdump: WARNING: dc0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on dc0, link-type EN10MB (Ethernet), capture size 96 bytes
on console 1:
ddev# kldunload if_dc
ukphy0: detached
miibus1: detached
dc0: detached
on console 2:
tcpdump: pcap_loop: read: Device not configured
0 packets captured
0 packets received by filter
0 packets dropped by kernel
I could not reproduce on current.
