Series applied with some minor modifications (added const qualifiers
where applicable, changed some data types).

Thanks a lot, this is nice work!

Hi,

Is it possible to use shell variables in the configuration file?
The use case I have is a script that sets variables such as IP address (
$SrcIP_Byte1 , $SrcIP_Byte2 , $SrcIP_Byte3 , $SrcIP_Byte4 ) then trafgen is
called using a standard configuration file, but the variables $SrcIP_Byte1
etc are referenced from within the config file itself
The alternative is that the shell script use 'sed' or other means of
manipulating the config file, but variables are so much easier

Thanks


Hi,

I added -D option which allows to .pass C preprocessor macro/define (with
combination of -p,--cpp option) and I think it can be
used similary to what you requested. The changes currently are only in
master branch in official repo. The same option was added
for bpfc.

Vadim Kochan
