Netmap pipe zero-copy with NIC buffer?

[Vincenzo Maffione]

Hi,
  Yes, when you nm_open("netmap:em3{2", ...), you're opening a netmap pipe
in the same netmap memory area as the one used by nm_open("netmap:em3",
...).
As a result, you can zero-copy packets from NIC rings to pipe rings.

What do you mean by "KB mode"?

Cheers,
  Vincenzo
