Jay,
I think that all comments to the patches were discussed and handled.
If you agree, can you please push then to the networking tree so they will be
merged into 2.6.24?
This includes the IPoIB patches (agreed with Roland).
Note that there are *no* patches to net/core (like in V5).
thanks

Hello Dave, hello Patrick,
this is the eigth post of the patch series that adds the PF_CAN
protocol family for the Controller Area Network.
Since our last post we have changed the following:
* Some changes in debug code, following suggestions from Joe Perches:
- Remove dynamically allocated
This patch adds the virtual CAN bus (vcan) network driver.
The vcan device is just a loopback device for CAN frames, no
real CAN hardware is involved.

You pointed out a key point: it's NOT acceptable if massive packet re-ordering
couldn¡¯t be avoided.
I debugged function tcp_ofo_queue in net/ipv4/tcp_input.c monitored
out_of_order_queue, found that re-ordering
becomes unacceptable with the softirq load grows.

Stack supports TCP and UDP over IP.
It works on top of netchannels [2] or packet socket
