Add the Device Feature List (DFL) feature id for the
High Speed Serial Interface (HSSI) Subsystem to the
table of ids supported by the uio_dfl driver.
The HSSI Subsystem is a configurable set of IP blocks
to be used as part of a Ethernet or PCS/FEC/PMA pipeline.
Like the Ethernet group used by the N3000 card, the HSSI
Subsystem does not fully implement a network device from
a Linux netdev perspective and is controlled and monitored
from user space software via the uio interface.

---
v3: change the name of this feature id to HSSI_SUBSYS and rewrite
the git message.
v2: add HSSI introduction and the git repo of Feature ID table.

Generally you should include the url for the dfl definitions. Can you add it here to the commit log ? Otherwise fine.

Yes, exactly. To someone not working the day-to-day working dfl they will have no clue where the fids come from. When a new one is added to the kernel, it should have a listing in dfl-feature-id repo. If it doesn't, there will be a future conflict.
