Usage example
|
|
|
-------------
|
|
|
|
|
|
-_smoltcp_, being a userspace networking stack, needs to be able to send and receive raw frames.
|
|
|
-This normally requires superuser privileges, but on Linux it is possible to create
|
|
|
-a _persistent tap interface_ that can be manipulated by a specific user:

|
|
+_smoltcp_, being a freestanding networking stack, needs to be able to transmit and receive
|
|
|
+raw frames. For testing purposes, we will use a regular OS, and run _smoltcp_ in
|
