Changing the PRE_DATA_SIZE value in src/vlib/CMakeLists.txt does not appear to
be that e
not sure to see which
functions I should use to create a new buffer and then to chain it to the
"main" one.

Changing makefiles is bad. cmake allows specifying custom values with -D or

I've just run few tests to be sure :
It's exactly that ! As long as the extension header is smaller or exactly equal
to 128 bytes, everything is fine.
Once it gets bigger than 128 bytes, it starts to go wrong and funk

Hi again Neale,

thus correct destination MAC address.

Hello all,
I'm trying to do some IPv6 in IPv6 encapsulation with no tunnel configuration.
The objective is to encapsulate the received packet in an other IPv6 packet
that will also "contain" a Hop-by-hop extension header. In summary, the
structure of the final packet will look like this : Out
12 matches
