How can I receive EAP packets?

How can I receive EAP packets?

[-- Attachment #1: Type: text/plain, Size: 688 bytes --]

Hi,everyone, I am using edkii to write EAP certified loader, I use EFI_ SIMPLE_ NETWORK.Transmit () to contract, want to use EFI_ SIMPLE_ NETWORK.Receive () to receive packets. It is found that ordinary IP packets can be received, but EAP packets cannot be received. How can I receive EAP package? I think there is a saying of hybrid mode in the program under windows. I want to know whether there is such a saying under EDK. In addition, I think EDK provides EFI_ EAP_ Protocol, I want to use this interface for user name and password authentication, but look at EFI_ EAP_ Protocol interface, do not know how to use, I would like to ask the relevant example code?
Thank you very much!

I don't know anything about "EAP", but I've CC'd the NetworkPkg owners.

The SNP protocol is low level interface to access network adaptor directly,
It's not designed to be used by application level, because it could only have
one consumer unlike other service binding network service protocols. So any
packet receive through SNP will be only delivered to this single consumer. 
If your "EAP certified loader" consumes SNP protocol, all upper layer network
stack (TCP/IP, etc) will stop work. So, at least use MNP protocol instead.

The MNP protocol "EnablePromiscuousReceive" allows you to receive packets
 that are sent to any MAC address. The IP protocol child instance with 0.0.0.0
station address allows you to receive packets that are send to any IP address.
Not sure if this is the "hybrid mode" you asking about.

As I know there is no driver to produce/consume EAP protocol in EDK2.

Thank you for your reply.
I will try to use MNP protocol.

>>Not sure if this is the "hybrid mode" you asking about.
Sorry, it's wrong. It should be "Promiscuous mode".

Do you have any examples or documentation of using MNP?

You may check the Ip4Dxe as example.

Hello, I am Jiangbo technology R&D, using edkii to write EAP certified
loader, I use EFI_ SIMPLE_ NETWORK.Transmit () to contract, want to use EFI_
SIMPLE_ NETWORK.Receive () to receive packets. It is found that ordinary IP
packets can be received, but EAP packets cannot be received. How can I
receive EAP package? I think there is a saying of hybrid mode in the program
under windows. I want to know whether there is such a saying under EDK. In
addition, I think EDK provides EFI_ EAP_ Protocol, I want to use this
interface for user name and password authentication, but look at EFI_ EAP_
Protocol interface, do not know how to use, I would like to ask the relevant
example code? I'm looking forward to your reply. Thank you very much!
