(Get the code!)
So, the end goal in this RFE is to remove sriov agent dependency on mac addresses entirely.
This will require some changes in neutron server as today mac address is required when agent wants to get device details.
IMO, the agent should rely on PCI address (and request details from neutron server based on PCI address) instead of MAC address.
As an intermediate step, since macvtap is broken today, we can either:
1. revert the commit in nova that exposed the issue [1]
2. move forward with the change in SR-IOV agent [2]
IMO we should do 1. and pursue the long term solution as this RFE suggests.
however if the community prefers 2. i'm OK with reworking patch[2].
In regards to the kernel <3.13 limitation, the only issue today is with CentOS 7, since CentOS 8 is around the corner, for U release we will not have this limitation as according to TC OpenStack needs to support the latest major distribution[3].
On a side note, once this limitation is removed, we can significantly reduce the amount of calls to 'ip link show' as proposed by [4], but this change is not related to this RFE.
I will be in Shanghai for the summit, we can maybe discuss this briefly there.
