Subject: Re: [PATCH v3 0/5] support flow subscription

Add support AVF can be able to subscribe a flow from PF.
Hi Jie,
Can you please provide more details, what does subscribing a flow from PF
mean?
The answer is in patch 1/5's commit log which would be better in cover letter
also :)
Hi Qi,
I checked all commit logs, but the feature wasn't clear to me, it can be
useful to elaborate more.
Is it the case that:
- PF create a flow rule
- VF subscribes to this rule, which means
- Packets will be sent to VF instead of PF
If above is correct, will both PF and VF receive packets, or only VF?
Can multiple VF subscribe to same rule?
Can PF destroy the rule while VF is subscribed?
How PF can prevent subscription to some flows from not trusted VF for
security concern?
...
Thanks,
ferruh
