One notable change introduced here is that, for DM_ETH, the name of the interfaces is corrected to the fmX-macY format, that avoids the referral to the MAC block names which were incorrect for FMan v3 devices (i.e. DTSEC, TGEC) and had weird formatting (i.e. FM1 at DTSEC6, FM1 at TGEC1). The legacy code is left unchanged in this respect.
