Make phyreg_writeops responsible for actually writing their
respective phy registers, rather than rely on set_mdic() to
do it on their behalf.
The only current instance of phyreg_writeops is set_phy_ctrl();
modify it to write the register on its own, while also correctly
handling reserved and self-clearing bits.
have_autoneg() does not need to check for MII_CR_RESTART_AUTO_NEG,
since the only time the flag comes into play is during set_phy_ctrl(),

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:

This reverts commit cd5be5829c.
Digging into hardware specs shows this does not
actually make QEMU behave more like hardware:
There are valid arguments backed by the spec to indicate why the version
of e1000 prior to cd5be582 was more correct: the high byte actually
includes a valid bit, this is why all guests write it last.
For rtl8139 there's actually a separate undocumented valid bit, but we
don't implement it yet.
To summarize all the drivers we know about behave in one way
that allows us to make an assumption about write order and avoid
spurious, incorrect mac address updates to the monitor.
Let's stick to the tried heuristic for 1.7 and
possibly revisit for 1.8.

This patch partially implements the e1000 interrupt mitigation mechanisms.
Using a single QEMUTimer, it emulates the ITR register (which is the newer
mitigation register, recommended by Intel) and approximately emulates
RADV and TADV registers. TIDV and RDTR register functionalities are not
emulated (RDTR is only used to validate RADV, according to the e1000 specs).
RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation
mechanism and would need a timer each to be completely emulated. However,
a single timer has been used in order to reach a good compromise between
emulation accuracy and simplicity/efficiency.
The implemented mechanism can be enabled/disabled specifying the command
line e1000-specific boolean parameter "mitigation", e.g.
qemu-system-x86_64 -device e1000,mitigation=on,... ...
For more information, see the Software developer's manual at
http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf.
Interrupt mitigation boosts performance when the guest suffers from
an high interrupt rate (i.e. receiving short UDP packets at high packet
rate). For some numerical results see the following link

Coverity complains about two overruns in process_tx_desc(). The
complaints are false positives, but we might as well eliminate
them. The problem is that "hdr" is defined as an unsigned int,
but then used to offset an array of size 65536, and another of
size 256 bytes. hdr will actually never be greater than 255
though, as it's assigned only once and to the value of
tp->hdr_len, which is an uint8_t. This patch simply gets rid of
hdr, replacing it with tp->hdr_len, which makes it consistent
with all other tp member use in the function.
