Subject: [PATCH net-next v2 00/10] net: phy: Add support for 2.5GBASET PHYs

Hello everyone,

This is the second iteration of the series introducing support for
2.5GBASET and 5GBASET to the network PHY infrastructure.

These 2 modes are described in the 802.3bz specifications, and allow to
use 2.5G and 5G speeds on cat5e/cat6 cables.

The required infrastructure code is added for 2.5GBASET and 5GBASET, but
only 2.5GBASET support is added to the Marvell10G driver. The reason is
because the 5GBASER interface mode used to communicate with the MAC
isn't implemented yet, and therefore this can't be tested.

This series has seen some rework since last time, see the full details
in the patches changelog. The main highlights are :

 - Patch 1 moves the Pause ans Asym_Pause parameters update after
   calling config_init. This allows us to change the phydev->supported
   modes in config_init, while still forcing some quirks taken from
   phydrv->features, to disable unsupported Pause modes. This was
   proposed by Andrew.

 - Patch 2 generalizes the way we mask-out modes we don't want to use
   when forcing the link speed through DT or ethtool, by walking through
   the PHY settings table, as proposed by Russell.

 - Patch 4 implements automatic setting of TM, FIBRE and Backplane bits
   from the list of supported linkmodes.

 - In Patch 5, we only read abilities from the PMA. Pause parameters
   aren't built from the genphy_c45_pma_read_abilities, as it was done
   in the previous iteration of the patch. We also amke use of
   linkmode_mod_bit to make sure we mask-out unsupported modes.

 - In Patch 8, we manually check for the PMA device id to see if we have
   to use a quirk when reading the 2.5G/5G Extended Abilities
