I currently have two tasks, including: - patch veth - patch eTSEC (gianfar) controller Since these tasks are gating our current work, we would really = appreciate any insight/pointers you may have and if possible, access to = a repository with preliminary veth modifications. Any assistance you = can provide in jump-starting our efforts would be greatly appreciated!
