Re: [libvirt] [PATCH v2 1/2] qemu: Remove network type limitation for qemuARPGetInterfaces

When we call qemuARPGetInterfaces to get IP from the host's arp

VIR_DOMAIN_NET_TYPE_DIRECT due to the host's arp table won't
include the
ip <-> mac entries about these type of backends.

OK - so not my area of expertise - I'm CC'g laine to get his opinion
just in case he missed this... I always get overly cautious since there
are many network types and this seems to be a rather far reaching change
of fetch...
You should reference commit e24d4c905 which added this code as it would
help focus on when the change was made.
Also since this really are disjoint problems, you should have created
separate patches especially since none of Sukrit's changes have anything
to do with this, but he's CC'd on the series because his change for
patch 2/2 did break something...
