You need to know each and every link layer you need to support.

The link layer part of the packet isn't supposed to be accessed outside of 
the link layer, so this isn't made easy.

If I am not wrong it simply hexdumps it with : between the octets. Length 
is known. But there may be special cases for some link layers.. see the 
source to make be sure. iproute just hext dumps it with :.
