them to new header files to keep igb from referring to them.

The system clock is necessary to implement PTP features. While we are
not implementing PTP features for e1000e yet, we do have a plan to
implement them for igb, a new network device derived from e1000e,
so add system clock to the common base first.

Before this change, e1000e_write_packet_to_guest() allocated the
receive descriptor buffer as an array of uint8_t. This does not ensure
the buffer is sufficiently aligned.
Introduce e1000_rx_desc_union type, a union type of all receive
descriptor types to correct this.

The register definitions in tests/qtest/libqos/e1000e.c had names
different from hw/net/e1000_regs.h, which made it hard to understand
what test codes corresponds to the implementation. Use
hw/net/e1000_regs.h from tests/qtest/libqos/e1000e.c to remove
these duplications.
E1000E_CTRL_EXT_TXLSFLOW is removed from E1000E_CTRL_EXT settings
because hw/net/e1000_regs.h does not have the definition and it is for
TCP segmentation offload, which does not matter for the implemented
tests.

This patch introduces emulation for the Intel 82574 adapter, AKA e1000e.
This implementation is derived from the e1000 emulation code, and
utilizes the TX/RX packet abstractions that were initially developed for
the vmxnet3 device. Although some parts of the introduced code may be
shared with e1000, the differences are substantial enough so that the
only shared resources for the two devices are the definitions in
hw/net/e1000_regs.h.
Similarly to vmxnet3, the new device uses virtio headers for task
offloads (for backends that support virtio extensions). Usage of
virtio headers may be forcibly disabled via a boolean device property
"vnet" (which is enabled by default). In such case task offloads
will be performed in software, in the same way it is done on
backends that do not support virtio headers.
The device code is split into two parts:
1. hw/net/e1000e.c: QEMU-specific code for a network device;
2. hw/net/e1000e_core.[hc]: Device emulation according to the spec.
The new device name is e1000e.
Intel specifications for the 82574 controller are available at:
http://www.intel.com/content/dam/doc/datasheet/82574l-gbe-controller-datasheet.pdf

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:

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
