Thanks! The patch was added to the develop branch. While the MAC address doesn't do anything special in the vport driver at the moment, the changed MAC address must be reflected to the bessd process. To implement this functionality we will need a custom handler rather than the generic eth_mac_addr() function.
from bess.
Can you give a few pointers on what that custom function would do ? I mean would it communicate back to user-space and then ( like a proxy) something would relay that information to bessd ? Or is there some other communication channel we can use for this purpose ?
from bess.
Oh, please ignore my previous comment. Since you are changing the MAC address of kernel-side interface (not the bess-side), bessd does not need to know the change.
Ideally, the kernel-side interface and the bess-side interface would need to have separate MAC addresses (especially for cases where bess is not running as a transparent bridge; e.g., IP router). Currently no interface is provided to do that, and BESS implicitly assumes those two sides of vport have the same MAC address.
