EtherTunnel - Don’t touch your MTU! #

EtherTunnel, the successor of RBridge is on its way to be released. The former name was often confused with the IETF TRILL Routing Bridge, so this relaunch is a good opportunity to address this..

The name EtherTunnel reflects exactly what it does: Tunneling Ethernet LANs, if you wish (or need) with ChaCha20/HMAC-SHA256 rotating 2^32 keys from preshared random material.

This without any MTU or MSS fumbling, precise allow/deny filtering capabilities (MAC addresses, vendor/OUIs and Ethertypes) and a custom fragmentation and reassembly algorithm that outperforms the generalized standard IP fragmentation.

Interesting to mention amid the recent issues: EtherTunnel is independent from any additional shared libraries, e.g. all cryptographic code, HMAC algorithms, random number combinators and compression functions are part of the development source code tree.
