Hi, Sajeesh
I think the intention of the UEFI spec is “multiple MNP child driver instances
(created by a same MNSBP)”. The MNP child instances under different NICs are
independent with each other, there won’t be a copy of packet from another NIC.

Subject: [edk2] MNP Rx filters Question.
Hello All,
There is one statement in the UEFI spec. Can someone brief about this comment
in the Spec.
Note: If multiple MNP child driver instances will receive the same packet
because of overlapping receive filter settings, then the first MNP child driver
instance will receive the original packet and additional instances will receive
copies of the original packet.
Note: Warning: Receive filter settings that overlap will consume extra
processor and/or DMA resources and degrade system and network performance.
If we have two identical NIC interfaces/functions, the Rx filters will be the
same, sice they advertise identical rx filter capabilities.
They will definitely overlap under such conditions. Then how does the above
statement makes sense. Can someone please
comment.
Thanks,
Sajeesh.
