Application specific parameters can be kept on the service processor. It is not possible to save
environment parameter changes within U-Boot as the saveenv command does not work.

Network Interfaces
The following network interfaces are available in U-Boot:
octmgmt0 (front-panel management interface)
octeth0 (1000BaseX interface to switch)
octeth4 (DXAUI interface 0 to switch)
octeth5 (DXAUI interface 1 to switch)

SerDes Configuration
Packets and control information can flow from the CN6880 via any of the SGMII, XAUI, DXAUI,
RXAUI, Interlaken, or PCIe interfaces. Internally CN6880 supports five SerDes quad-lane
modules (QLMs) for a total of 20 SERDES lanes.
For the default configuration of ATCA-9405 (where the Packet Processors are interconnected
via Interlaken Interface), one PCI Express, one Interlaken, two DXAUI and two RXAUI interfaces
are provided.
Note that ATCA-9405-ILK-MODULE must be assembled on this version.
The corresponding QLM mode strapping is listed in the table below. The QLM reference clock
must be configured according to the IO interface standard used.
