These registers appear in Intel's specs, but were not implemented.
These registers are now implemented trivially, i.e. they are initiated
with zero values, and if they are RW, they can be written or read by the
driver, or read only if they are R (essentially retaining their zero
values). For these registers no other procedures are performed.
For the trivially implemented Diagnostic registers, a debug warning is
produced on read/write attempts.
PLEASE NOTE: these registers will not be active, nor will migrate, until
a compatibility flag will be set (in a later patch in this series).
The registers implemented here are:

This fixes some alignment and cosmetic issues. The changes are made
in order that the following patches in this series will look like
integral parts of the code surrounding them, while conforming to the
coding style. Although some changes in unrelated areas are also made.

Using mii-tool (on F20-live), the following output is produced:
SIOCGMIIREG on ens3 failed: Input/output error
ens3: no autonegotiation, 1000baseT-FD flow-control, link ok
The first line (SIOCGMIIREG error) is due to mii-tool's inability
to read the PHY auto-negotiation expansion register.
On the second line, "no autonegotiation" is wrong, and caused by
the absence of a flag in the link partner ability register which
would indicate that our link partner has acked us. This flag is
listed as "reserved" in the Intel e1000 manual, but mii-tool uses
it as LPA_LPACK from /usr/include/linux/mii.h.
This patch adds read access to PHY_AUTONEG_EXP and defines the
link partner ack flag, allowing mii-tool to generate output as
normally expected:
ens3: negotiated 1000baseT-FD flow-control, link ok
