From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>
Move the ifaceMacvtapLinkDump and ifaceGetNthParent functions
into virnetdevvportprofile.c since they are specific to that
code. This avoids polluting the headers with the Linux specific
netlink data types
* src/util/interface.c, src/util/interface.h: Move
ifaceMacvtapLinkDump and ifaceGetNthParent functions and delete
remaining file
* src/util/virnetdevvportprofile.c: Add ifaceMacvtapLinkDump
and ifaceGetNthParent functions
* src/network/bridge_driver.c, src/nwfilter/nwfilter_gentech_driver.c,
src/nwfilter/nwfilter_learnipaddr.c, src/util/virnetdevmacvlan.c:
Remove include of interface.h
