Hi Lennert,
I am not sure whether it is driver issue or something else. Here is the
scenario.
**** NOTE: This is stock kernel without any modifications.
brctl addbr aUser
brctl addif aUser eth1 (Intel Fiber Gig card - e1000 driver)
brctl addif aUser eth2 (BroadComm copper gig card -- This is onboard card
on Dell 2550 Poweredge Server - tg3 driver)
If I send DNS queury packet (ping www.cmu.edu), after putting pkt on wire
(eth2 side) it gets crashed in 'dev_queue_xmit' function.
I think packet flows as following.
br_handle_frame_finish()
dst != NULL
br_forward(dst->dst, skb)
__br_forward
__br_forward_finish
__br_queue_push_xmit
dev_queue_xmit
I don't know, where exactly in dev_queue_xmit. I can send you image and
other OOPS addresses.
Unfortunately, I can't compile bridge in kernel. I have to compile as
module. I hope this will NOT be a problem in debugging.
Please let me know.
Many Thanks,
-Kunal
