fa6ed31dd9
Add no functional changes, but rename enablement functions, variables etc. that are used in teaming driver transmit decisions. Since rx and tx enablement are still coupled, some of the variables renamed in this patch are still used for the rx path, but that will change in a follow-up patch.
