NetBSD isc.home.flame.org 5.1_STABLE NetBSD 5.1_STABLE (XEN3_DOM0) #0: Sun Jan 9 10:04:51 UTC 2011 root@isc.home.flame.org:/usr/src/sys/arch/amd64/compile/XEN3_DOM0 amd64
>Description:
If I enable checksum offloading on my "wm0" interface with:
ifconfig wm0 ip4csum tcp4csum udp4csum tso4 tcp6csum udp6csum tso6
which enables all available offloading functions, when NetBSD configures the bridge with:
create
!brconfig $int add wm0 up
the interface stops receiving packets. tcpdump shows traffic on the interface, and it appears transmitting packets continues to function.
>How-To-Repeat:
>Fix:
Disable all offloading functionality, and the interface works.

bridge+offload problems have been fixed by me and rin@. At least netbsd-9 have those fixes. Is it OK to close this ticket?

Yes.
While there, please remove me from all future NetBSD mailings. All bugs, all=
periodic reminders, everything. I was told to fuck off years ago because I d=
ared ask a question about kernel internals.=20
