vpp-manager: replicate eui64 ll addr on linux tap.#956
Merged
Conversation
This patch will replicate the eui64 link local address we read on the linux uplink before startup (in ifState) on the tap replica we create after starting VPP. We will still wait for linux to assign a new link local address to the tap, add the eui64 one and remove the newly created, so that we do not run into a situation where we have two link local addresses as VPP only supports one. This addresses issue with anti mac spoofing mechanism that prevent us from changing our link local address. This is also cleaner as the newly generated address will only be temporary.
