Stefan Weil c4c270e227 eepro100: Add more i825xx devices
The new devices added here are still not functional -
partially because some patches are still missing,
partially because I cannot test them. Nevertheless
they belong to the same family and will be supported
by this driver some day.

As soon as they work, they will also be added to hw/pci.c.

Stefan Weil 3031efabd0 eepro100: Remove unused device status entries
A lot of entries are unused (they were added by copy + paste
from other drivers during development of eepro100.c).

Removing them from nic_save, nic_load makes any
old saved status incompatible, so a new version
for the virtual machine data was needed, too.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

 Correct the logic of determining devices that supports
 extended TxCB: only the 82557 do not support it.

Gerd Hoffmann 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.

Reimar Döffinger 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.

Naphtali Sprei 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.

Jan Kiszka 8217606e6e Introduce reset notifier order
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.

aliguori 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.
