-Description: Skip mac2iface test for esoteric interfaces
- mac2iface takes a MAC address as argument and returns the corresponding
- interface (if any).
- The mac2iface tests will however invoke mac2iface with invalid MAC addresses
- when esoteric network interfaces are present on the system. As an example,
- armhf autopkgtest runners in Ubuntu have gre interfaces configured so the
- test-suite fails.
- .
- We now ensure that the test-suite calls mac2iface with only valid MAC
- addresses.
- .
- Furthermore, sometimes the same MAC address is assigned to more than one
- interface on the system (this is true for VLAN interfaces for instance). This
- confuses mac2iface, which returns only the first match. This scenario is
- possibly more of a nvme-stas bug than a test-suite bug, but for now we will
- just skip the interfaces that have a duplicate MAC address.
- .
