Netmap with bonded interfaces

[Vincenzo Maffione]

Hi,
  It is an expected behaviour that you cannot open eth4 and eth5 if they
are bond, as the device are being used by the lagg pseudo-driver.
Since this driver does not have netmap support for the moment being, there
is no way you can get the native mode performance if you use lagg.

If you just need some failover in your application, you could just
implement a simple failover mechanism in your application (e.g. the
application opens both netmap:eth4 and netmap:eth5, and decides which one
to use for transmission depending on which one is up...).

Cheers,
  Vincenzo
