This patch series adds support for 2.GbE in 10GBaseT mode and
rx-adaptation support for Yellow Carp devices.

1) Support for 2.5GbE:
   Add the necessary changes to the driver to fully recognize and enable
   2.5GbE speed in 10GBaseT mode.

2) Support for rx-adaptation:
   In order to support the 10G backplane mode without Auto-negotiation
   and to support the longer-length DAC cables, it requires PHY to
   perform RX Adaptation sequence as mentioned in the Synopsys databook.
   Add the necessary changes to Yellow Carp devices to ensure seamless
   RX Adaptation for 10G-SFI (LONG DAC), and 10G-KR modes without
   Auto-Negotiation (CL72 not present)
