I probably should have sent them with subject-prefix "PATCH net-next" !?

Yes, I'm currently trying to push a driver for the Marvell88Q2220
100BASE-T1/1000BASE-T1 PHY. It supports autonegotiation and with an
additional patch to function genphy_c45_baset1_an_config_aneg which is
not part of the series it is possible to set the advertised speed.
I probably should send all patches as a series including the driver ?
