Say I'm the server, a client is connected to me using TCP. How can I get the client's MAC address from it's socket using the SDL_net library?
Thank you for your help.

This has nothing to do with SDL, but the MAC address is only a link-level address and is never transported outside the link. The only MAC address you, as the server, will see is the last node the packace arrived from, likely your server's gateway or router. That is, incoming TCP-data is wrapped in an IP message that has your IP as the destination and the client's IP as the source, but it is wrapped in an ethernet frame with your MAC as the source and the last gateway or router's MAC address as the source.
