The patches apply on net-next. Changes since v4: - added Reviewed-by and Tested-by tags on first 2 patches, the others are changed are affected by changes in patch 3/6, so I did not add the tags, except for 5/6, which is just macro renaming - patch 3 was changed: the serdes_get_lane returns 0 on success (lane was discovered), -ENODEV if not lane is present on the port, and other error if other error occured. Lane is put into a pointer of type u8 - patches 4 and 6 were affected by this (error detecting from serdes_get_lane) - Andrew's complaint about the two additional parameters (allow_over_2500 and make_cmode_writable) was addressed, by Vivien's advice: I put a new method into chip operations structure, named port_set_cmode_writable. This is called from mv88e6xxx_port_setup_mac just before port_set_cmode. The method is implemented for Topaz. The check if cmodes over 2500 should be allowed on given port is now done in the specific port_set_cmode() that requires it, thus the allow_over_2500 argument is not needed Again, tested on Turris Mox with Peridot, Topaz, and Peridot + Topaz.
