[PATCH 21/33] Rename low level macvlan creation APIs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

Rename ifaceMacvtapLinkAdd to virNetDevMacVLanCreate and
ifaceLinkDel to virNetDevMacVLanDelete. Strictly speaking
the latter isn't restricted to macvlan devices, but that's
the only use libvirt has for it.

* util/interface.c, util/interface.h,
  util/virnetdevmacvlan.c: Rename APIs
