cxgbe and netmap

[Alexander V. Chernikov]

Hello list!

FreeBSD has netmap support for chelsio T5 cards, which is amazing.
The great thing about implementation is that you can play with
traffic-generating applications without affecting "main" OS interface,
which has always been a problem for Intel cards.
However, this approach (having additional netmap-only ifp) turns to be a
bit problematic for netmap-based networking elements participating in
routing.

In Intel case you can configure all your interfaces, run routing daemon,
run netmap application and punt all to-host traffic  to kernel via host
pipes.
It looks like I can't do this using current implementation: mac
addresses are different for main/netmap interfaces so I can't run
routing daemon on main interface (or sub-interfaces).
I also can't run routing daemon on top of ncxgbe* interface since it
appears to ignore non-netmap-derived traffic..

Is it possible to make ncxgbe* interfaces behave more like ordinary ones?
