Hi all,

I had a quick question about some of the implications of sharing packet
buffer memory between multiple interfaces. Assuming an arbitrary amount of
interfaces (> 2) are linked together with NM_OPEN_NO_MMAP and share the
same memory, would this have any issues with lock contention?

Sorry in advance if this is the wrong place to post, I had seen several
other archives about Netmap on this mailing list and I thought it was the
most appropriate place.

Regards
