Like other Intel devices, e100 (eepro100) uses little endian byte order.
This patch was tested with these combinations:
i386 host, i386 + mipsel guests (le-le)
mipsel host, i386 guest (le-le)
i386 host, mips + ppc guests (le-be)
mips host, i386 guest (be-le)
mips and mipsel hosts were emulated machines.

QEMU sends frames smaller than 60 bytes to ethernet nics.
Such frames are rejected by real NICs and their emulations.
To avoid this behaviour, other NIC emulations pad received
frames. This patch enables this workaround for eepro100, too.
All related code is marked with CONFIG_PAD_RECEIVED_FRAMES,
so we can drop this in case QEMU's networking code is
ever changed.

The virtio serial specification requres that the values in the config
space are encoded in native endian of the guest.
The qemu virtio-serial code did not do conversion to the guest endian
format what caused problems when host and guest use different format.
This patch corrects the qemu side, correctly doing host-native <->
guest-native conversions when accessing the config space. This won't
break any setups that aren't already broken, and fixes the case
of different host and guest endianness.

So far we set IRR for edge IRQs even if the pin is masked. If the guest
later on unmasks and switches the pin to level-triggered mode, irr will
remain set, causing an IRQ storm. The point is that setting IRR is not
correct in this case according to the spec, and avoiding this resolves
the issue.

Some commands are supposed to report a Not Ready Condition (i.e. they require
a medium to be present in order to execute successfully). Instead of
duplicating the check in each command implementation, let's add a flag and
check it before calling the command.
This patch only converts existing checks, it does not introduce new checks for
any of the other commands that can/should report a Not Ready Condition.
