Section 13.7.15 Receive Length Error Count says:
> Packets over 1522 bytes are oversized if LongPacketEnable is 0b
> (RCTL.LPE). If LongPacketEnable (LPE) is 1b, then an incoming packet
> is considered oversized if it exceeds 16384 bytes.
> These lengths are based on bytes in the received packet from
> <Destination Address> through <CRC>, inclusively.
As QEMU processes packets without CRC, the number of bytes for CRC
need to be subtracted. This change adds some size definitions to be used
to derive the new size thresholds to eth.h.

Before this change, e1000 and the common code updated BPRC and MPRC
depending on the matched filter, but e1000e and igb decided to update
those counters by deriving the packet type independently. This
inconsistency caused a multicast packet to be counted twice.
Updating BPRC and MPRC depending on are fundamentally flawed anyway as
a filter can be used for different types of packets. For example, it is
possible to filter broadcast packets with MTA.
Always determine what counters to update by inspecting the packets.

The bytes and packets counter registers are cleared on read.
Copying the "total counter" registers to the "good counter" registers has
side effects.
If the "total" register is never read by the OS, it only gets incremented.
This leads to exponential growth of the "good" register.
This commit increments the counters individually to avoid this.

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.

e1000x_is_vlan_packet() had a pointer to uint8_t as a parameter, but
it does not have to be uint8_t. Change the type to void *.

PCIDeviceClass and PCIDevice are defined in pci.h. Many users of the
header don't actually need them. Similar structs live in their own
headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in
pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h,
PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and
PCIESlot in pcie_port.h.
Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with
the code that needs them. Adjust include directives.
This also enables the next commit.

In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).
The previous commits have left only the declaration of hw_error() in
hw/hw.h. This permits dropping most of its inclusions. Touching it
now recompiles less than 200 objects.
