hehe, it is not about typing. The setup is done by a script.
And we both know that getting a patch upstream is much more work than
typing a few lines of hacky bash scripts.
Since I want a decent solution and feedback I'm bringing this up here.

I could also just go with my in-house patch and don't tell anyone...

If having a bridge plus u32+mirred for STP bypass is the preferred solution,
I'm fine with it.
So far we use the kernel patch and didn't test the mirred-bypass a lot.
My fear was that mirred rules from eth0 to eth1 and back might cause a
loop or confuse the bridge...
