It is not nice to duplicate the pcap struct and macros and have dpdk versions of 
them, it may have long term maintanance issues too.

What are the clashes in question?

If they are macros, can the issue solved after undefining some after including 
'pcap.h'?

And at the end of the day, shouldn't we need to resolve these clashes globally 
since we may hit same things with other PMDs or libraries as we enable them. I 
am for a global solution instead of these changes in pcap, but I guess question 
is how possible that global solution is..
