Andreas Färber 83f7d43a9e qom: Unify type registration
Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

Anthony Liguori 39bffca203 qdev: register all types natively through QEMU Object Model
This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

To avoid this behaviour, other NIC emulations pad received

target endianness is not of their concern, so we need to push things

This patch adds a parameter to cpu_register_io_memory that allows a

native endian, because that's the same behavior as before.

Stefan Weil 010ec62934 eepro100: Add support for multiple individual addresses (multiple IA)
I reviewed the latest sources of Linux, FreeBSD and NetBSD.
They all reset the multiple IA bit (multi_ia in BSD) to zero,
but I did not find code which sets this bit to one
(like it is done by some routers).

Running Windows guests also did not set this bit.

Intel's Open Source Software Developer Manual does not
give much information on the semantics related to this bit,
so I had to guess how it works. The guess was good enough
to make the router emulation work.

Related changes in this patch:
* Update naming and documentation of the internal hash register.
  It is not limited to multicast, but also used for multiple IA.
* Dump complete configuration register when debug traces are enabled.
* Debug output when multiple IA bit is set during CmdConfigure.
* Debug output when frames are received because multiple IA bit is set,
  or when they are ignored although it is set.
