VirtIOSerialDevice is like VirtIOSerialPort with just the first two
fields, which makes it pretty pointless. Using VirtIOSerialPort
directly works equally well and is less confusing.

The SD_STATUS and SEND_NUM_WR_BLOCKS commands are supposed to cause
the card to send data back to the host. However sd.c was missing the
state change to sd_sendingdata_state for these commands, with the effect
that the Linux driver would either hang indefinitely waiting for
nonexistent data (pl181) or read zeroes and provoke a qemu warning
message (omap).

Nothing prevented IRQ sharing on the ISA bus in principle. Not all
boards supported this, neither each and every card nor driver and OS.
Still, there existed valid IRQ sharing scenarios, (at least) two of them
can also be found in QEMU: >2 PC UARTs and the PREP IDE buses.
So remove this artificial restriction from our ISA model.

qemu makes it possible to disable link at tap which is not communicated
to the guest but causes all packets to be dropped.
When vhost-net is enabled, vhost needs to be aware of both the virtio
link_down and the peer link_down. we switch to userspace emulation when
either is down.

The spec says: Any descriptor with a non-zero status byte has been
processed by the hardware, and is ready to be handled by the software.
Thus, once we change a descriptor status to non-zero we should
never move the head backwards and try to reuse this
descriptor from hardware.
This actually happened with a multibuffer packet
that arrives when we don't have enough buffers.
Fix by checking that we have enough buffers upfront
so we never need to discard the packet midway through.

The e1000 spec says: if software statically allocates
buffers, and uses memory read to check for completed descriptors, it
simply has to zero the status byte in the descriptor to make it ready
for reuse by hardware. This is not a hardware requirement (moving the
hardware tail pointer is), but is necessary for performing an in–memory
scan.
Thus the guest does not have to clear the status byte. In case it
doesn't we need to clear EOP for all descriptors
except the last. While I don't know of any such guests,
it's probably a good idea to stick to the spec.
