Add Layer3::Arista.
Work around Net-SNMP's failure to load IF-MIB because it prefers the obsolete RFC1213-MIB more completely: add the new ifOperState values explicitly (e.g., lowerLayerDown, dormant, notPresent,...)

There is a collision between data in C<IF-MIB> and C<RFC-1213>.

For devices that fully implement C<IF-MIB> it might return 7 for
