[libvirt] [PATCHv2 0/2] macvtap: don't use netlink to save/set mac for macvtap+passthrough+802.1Qbh

These two patches are the v2 of a single patch that I sent last week: https://www.redhat.com/archives/libvir-list/2015-August/msg00889.html At the time I sent that patch, I had no hardware to test it on, but was operating on a misunderstood assumption - someone in the know had told me that libvirt didn't need to save/restore the MAC address of VFs for 802.1Qbh macvtap passthrough, and I extrapolated from there that we didn't need to *set* the MAC address of the VF either. This makes sense, since that is what happens for 802.1Qbh *device* passthrough, but based on my own tests the 802.1Qbh "associate" fails unless libvirt sets the VF's MAC address prior to associate. So this patch takes a different approach from V1 - instead of completely skipping the save/set/restore of MAC address for VFs that are using 802.1Qbh, it still does it, but uses the "old" method of ioctl(SIOCGIFHWADDR) and ioctl(SIOCSIFHWADDR). I *did* have the proper hardware to test this time, and it works (both for a Cisco VMFEX card using 802.1Qbh and for an Intel 82576 card with straight macvtap passthrough).
