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
