c4a0ad47dd Only rename the virtual Azure Hyper-V network interface
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1964822
Upstream: RHEL-only

Currently, vmcore dumping to remote fs gives a warning "eth0: Failed to
rename network interface 3 from 'eth0' to 'kdump-eth0': File exists" on
Azure Hyper-V VM with accelerated networking because it uses a physical
NIC for accelerated networking [1] and the backing physical NIC has the
same MAC address as the virtual NIC. In the kdump initrd, an udev rule
will try renaming NICs with the given MAC address and fails as expected
since there are two NICs having the same MAC address. This udev rule is
created automatically when specifying the dracut cmdline
"ifname=<interface>:<MAC>". For the case of Azure Hyper-V VM with
accelerated networking, only the virtual network interface need to be
renamed. So create an udev rule manually.

c95039410e Don't rename Azure Hyper-V network interface
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1964822
Upstream: RHEL-only

Currently, vmcore dumping to remote fs gives a warning "eth0: Failed to
rename network interface 3 from 'eth0' to 'kdump-eth0': File exists" on
Azure Hyper-V VM with accelerated networking because it uses a physical
NIC for accelerated networking [1] and the backing physical NIC has the
same MAC as the virtual NIC. There is no need to rename a Hypver-V
interface in this case which also leads the aforementioned warning.
