The reference implementation of hv_get_dns_info which is in the tree uses
/etc/resolv.conf to get DNS servers and this does not require to know which
NIC is queried. Distro specific implementations, however, may want to
provide per-NIC, fine grained information. E.g. NetworkManager keeps track
of DNS servers per connection.
Similar to hv_get_dhcp_info, pass NIC name as a parameter to
hv_get_dns_info script.
