If it is accepted into mainline, be sure to send Stephen somedocumentation on this feature so he can add it to the net:bridge docs.When features like this aren't documented, no one knows how to usethem. I just ran into this issue with the 2.6.27+ "sticky" bridge MACfeature. I'd also be willing to help keeping the bridge docsup-to-date. Please let me know if you or Stephen want me to do this.Bridging is really important for OpenVZ and othercontainer/paravirtualization technologies so keeping docs up-to-dateis becoming more important. It can be useful to have anon-kernel-developer like me document the functionality.
