Hello all,
is there a way to get the source MAC address for a decrypted IPsec protected 
UDP packet? For unencrypted data I would use RAW sockets, but this obviously 
fails for encrypted data.

In either case, you would have to use PACKET sockets as INET raw sockets won't 
give you the link-layer headers. But yeah, that would mean deciphering the 
packets in userland.
