SNAP format support？

[rogeroger-yu]

Hello, Vincent
Is it possible to configure the lldp protocol to transmit in the SNAP format?

[vincentbernat]

No, there is currently nothing for that. Are you using a non-Ethernet network?

[rogeroger-yu]

Yes, some requirements will use it.

To implement that, I would need some way to test that. How such an interface appears for Linux? Could you share the output of ip -d l l dev XXX?

[rogeroger-yu]

Sorry, there is no actual environment at present, just have this demand. ：）
After that, I will update the information. Thanks！！！

Hi, Vincent! I recently docked such a device：LAN Switching Configuration Guide
It can set the encapsulation format of LLDP frames to SNAP. The result of my capture is as follows：

I tried to expand the SNAP function based on your project, can I push the changes up and ask you to review the code for me?
