Hello

I wonder if it is = possible for a sequence of processes to communicate
using th= e DPDK shared memory packet interface (memif) PMD?

If for example A, B, C and D are DPDK applications, is the following commu= nication
possible to implement using the DPDK memif PMD?
A =C2=A0 <-> =C2=A0 B=C2=A0=C2=A0 <-> =C2=A0 C=C2=A0=C2=A0 &l= t;-> =C2=A0 D
That is, processes A and B have a duplex communi= cation in this example.
Processes B and C have a duplex commu= nication and the same applies to processes C and D.

If this is possible, could you please explain what EAL parameters shall b= e used
for the four processes in this example?

Thanks
Staffan
