ced5296ab7 eepro100: Use symbolic names and BIT macros in binary operations
Instead of magic numbers like 0x8000, symbolic names are used
for the SCB command and status bits.

There are too many configuration bits to use symbolic names
there, too. Using the BIT macro is a little help when comparing
code and documentation.

For the same reason, some other constants were replaced by
the BITS macro.

da51e79b7f eepro100: Support gpxe boot for all eepro100 devices

* Add these GPXE ROM files using new naming convention
  (as discussed on qemu-devel). Both files were created
  with http://rom-o-matic.net/, PCI vendor / device ids
  as in ROM filenames and option BANNER_TIMEOUT = 0.

* Remove old PXE ROM file for i82559er.

* Update pc-bios/README (and sort entries).

f3a52e503b eepro100: Restructure code (new function tx_command)
Handling of transmit commands is rather complex,
so about 80 lines of code were moved from function
action_command to the new function tx_command.

The two new values "tx" and "cb_address" in the
eepro100 status structure made this possible without
passing too many parameters.

In addition, the moved code was cleaned a little bit:
old comments marked with //~ were removed, C++ style
comments were replaced by C style comments, C++ like
variable declarations after code were reordered.

Simplified mode is still broken. Nor did I fix
endianess issues. Both problems will be fixed in
additional patches (which need this one).

938a632402 eepro100: Update ROM file support
Use new way to associate ROM files to devices.

Currently, there is only a ROM file for i82559er
included in QEMU, so the patch does not add
.romfile for the other devices.

When flexible mode is fixed in eepro100, adding
more ROM files will be possible. It should be
possible to create them from pxe-i82559er.bin,
because etherboot uses the same driver for all
eepro100 devices (only PCI ids differ).

Maybe it is even possible to create a single
pxe-i8255x.bin which supports all eepro100 devices
(not supported with current etherboot).

3706c43f02 eepro100: Remove unused device status entries
Once upon the time when QEMU hacking was fun
there was a brave knight who wanted to have
a driver for a special intel nic.

So he started by cloning ne2000.c which also
meant that the new born eepro100.c was
immediately three years old.

Other knights who also wanted to have fun and
take their part in the battle thought that it
would be a good idea to remove stupid code
which says "missing nic load, missing nic save".

They saved everything they saw, man and women,
ne2000 code and runtime address offsets, and
put all saved elements in a prison called
vm data.

When the first knight came back and noticed
the unhappy prisoners, he wanted to set them
free. But the keepers of the keys told him
that they would have to stay there forever
for compatibility reasons.

So our brave knight now takes a new effort
to save the souls of the poor prisoners by
removing their names.

Their bodies will have to rot in the dungeons
of compatibility forever, watched by the
keepers of the keys.

eepro100.c shouldn't have the need to do this in its local header file.

And I recently started getting this:

/home/amit/src/qemu/hw/eepro100.c:112: error: two or more data types
in declaration specifiers
/home/amit/src/qemu/hw/eepro100.c:112: warning: useless type name in
empty declaration
make[1]: *** [eepro100.o] Error 1

so just remove the typedef and include <stdbool.h> instead.

81a322d4a1 qdev: add return value to init() callbacks.
Sorry folks, but it has to be.  One more of these invasive qdev patches.

We have a serious design bug in the qdev interface:  device init
callbacks can't signal failure because the init() callback has no
return value.  This patch fixes it.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault.  This patch fixes it.

With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

24e6f3551f fix stack buffer overflows in eepro100.c tx
Hello,
the real world issue is that the hardware allows sends up to 2600 bytes,
and for some reason FreeBSD sometimes sends frames larger than the
ethernet frame size (102+1460 is the maximum I have seen so far),
overflowing the on-stack tx buffer of the driver.
Independent of that, the code should avoid allowing the guest to
overwrite the stack.
This is a minimal patch to fix the issue (you could leave out the size
change of the buf array as well, networking still seems to work either
way). Obviously there are better ways to handle it, but a proper fix IMO
would involve first getting rid of the code duplication and given the
number of patches pending for that code I see no point in working on that now.

3f9cb1c14d hw/eepro100.c: Use extended TBD only where applicable
Bug fix for segfault when run as i82551 HW:
Use Extended TBD only when HW supports it (i82558 and up).

Added assertions to guard from such buffer overflow
Introduce the MAX_TCB_BYTE_COUNT macro
Allocate buf big enough as HW needs (MAX_ETH_FRAME_SIZE -> MAX_TCB_BYTE_COUNT)

I don't feel 100% OK with the "s->device >= i82558B" condition
since it relies on the numeric (hex) value of those defines, which currently
is correct, but changes (which I don't forsee now) might break it.

Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

cef3017cd7 Clean some PCI defines (Stefan Weil)
this patch adds some more defines from linux/pci_regs.h to
hw/pci.h. There is now no longer a need to define them in
eepro100.c, so they were removed there.

Some defines from linux/pci_regs.h had similar, but not
the same defines in hw/pci.h (PCI_REVISION_ID / PCI_REVISION,
PCI_SUBSYSTEM_VENDOR_ID / PCI_SUBVENDOR_ID,
PCI_SUBSYSTEM_ID / PCI_SUBDEVICE_ID).

I suggest to use the "standard" from linux/pci_regs.h and
replace the "old" Qemu ones. To facilitate the migration,
my patch does not remove the old defines but marks them
as obsolete. After a migration to the "standard" defines,
pci.h could use linux/pci_regs.h which is far more complete.

The patch is needed for an updated maintainer version of
hw/eepro100.c which I'd like to see in Qemu stable.

 * Remove declarations already declared in header file from eepro100.c
 * Add missing declarations from pci_regs.h to pci.h
