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.
