trafgen: proto: Allow to set field with variable length
It is quite tricky to set field value with a variable length (i.e. DNS query name), to make it possible the field needs to be added to header with 'len=0' in that case there will be no any payload allocation, but only while setting the field value the packet will be appended with a real length bytes and after the field needs to be relocated to the right place. Also add 'len' parameter to *_set_bytes(...) functoins to have better control over it. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
