Greetings Andrew,
The patch compiles and works as expected.
I noticed something strange btw - swi1: net was consuming 100% WCPU
(shown on top -S)
but I'm not sure this have something to do with your patch, as I can't
reproduce it right now ..

Hi,
May be a stupid questions, but:
1) There are zero matches of IFCAP_TOE in kernel sources .. there is not
support for TOE in 7.0, but may be this is work in progress for 8-current?
Yes, its in current only. Just remove IFCAP_TOE.
2) In #define BRIDGE_IFCAPS_MASK (IFCAP_TOE|IFCAP_TSO|IFCAP_TXCSUM) - TOE
should be repleaced with RXCSUM or just removed?
3) Why RX is never checked? In my case this doesn't matter because em turn
off both TX and RX if only one is disabled, but probably there is a
hardware,
that can separate them e.g. RX disabled while TX enabled?
Rx does not matter, whatever isnt offloaded in hardware is just computed
locally such as checking the cksum. Its Tx that messes up the bridge, if
a outgoing packet is generated locally on an interface that has Tx
offloading, it may actaully be sent out a different bridge member that
does not have that capability. This would cause it to be sent with an
invalid checksum for instance.
The bridge used to just disable Tx offloading but this patch you are
testing makes sure each feature is supported by all members.
4) I'm not sure why bridge should not work with two interfaces one of which
support TX and the other does not? At least if I turn on checksum offload
only on one of the interfaces the bridge is still working ...

This patch should do that, are you able to test it Stefan?
cheers,
Andrew
P.S. I saw very good results with netisr2 on a kernel from p4 before few
months .. are there any patches flying around so I can test them with
7-STABLE? :)
