The first patch in the series generalizes the way we build the list of supported modes in C45 PHYs, relying on the various modes exposed in the PMA registers. It extracts the logic from the marvell10g driver. The second patch adds the new register definitions from the 802.3bz specifications, and adds the generic code to handle both 2.5GBASET and 5GBASET. The third patch allows to automatically detect whether or not a PHY supports 2.5GBASET and 5GBASET, by reading the PMA abilities. Patches 4 and 5 add support for 2.5GBASET into the marvell10g driver, with a workaround for incorrect abilities being reported by the 88X3310 and the 88E2010 PHYs. (see patch 5). Patch 6 adds support for 2.5GBASET in the PPv2 ethernet driver, thus enabling support for that mode on the MacchiatoBin. Finally, patch 7 introduces support for the 88x2110 PHY, which is very similar to the 88x3310, the only difference being the lack of Fiber support. The 88x2110 already reports the correct abilities from it's PMA, and thus doesn't require the workaround implemented in patch 5 for 2.5GBASET to work. This is based on work originally done by Antoine Tenart. This patch series was tested on the MacchiatoBin, a custom board using a 88e2010, and another using a 88x2110. The 88x2110 support is enclosed in the series to better show the need for the workaround in the 88x3310, feel free to tell me if we should handle such hardware issues in another way, or if support for that PHY should be submitted separately. At this point, future development adding 5GBASET to Marvell PHYs should be straightforward, but this isn't included in the series since I lack any hardware to test the 5GBASE-R mode that the PHY uses to connect to the MAC in that case. Thanks to Andrew for doing the rework of the link_mode representation this series depends on.
