Hey, While having a discussion with Sasha from Intel. I noticed link partner advertised support is broken in ethtool 5.7. Sasha hinted to me, the new API that ethtool is using.
I see the actual cause in dump_peer_modes() in netlink/settings.c, that the mask parameter is set to false for dump_link_modes, dump_pause and bitset_get_bit. Regards, Jamie Gloudon
