Commit 15e89f5916c9e82347cbd1fd416db3e348bab426
removed this setting, but it is still needed.
Without this patch, e100 device drivers using
interrupts don't work with qemu.
See other nic emulations which also set the
PCI interrupt pin.

pci_add_capability automatically updates PCI status and
PCI capability pointer, so use it. Use pci_reserve_capability

SCBStatus is readonly, but most drivers which were derived
from the old Linux eepro100.c do a word write to this address
when they want to acknowledge interrupts.
So we have to mask these writes here.
The patch also removes old unused code for status read / write.

eepro100 uses macros which rely on a specific
local variable name (pci_conf) which is scary.
Some of the uses are wrong or unnecessary,
remove them. The rest are small in number, open-code
them using pci_set_xx functions.

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.

Only two boot ROM files are needed for all 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.
It was replaced by gpxe-eepro100-80861209.rom.
* Update pc-bios/README (and sort entries).
Full support still needs additional eepro100 fixes.

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).

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).

* Rename pxe-eepro100.bin to pxe-i82559er.bin.
The other devices supported by eepro100.c need
additional pxe boot ROM images.
* Call rom_add_option during initialisation.
The code won't work with two or more different
eepro100 devices, because it only adds one option
ROM, but this use case is perhaps never needed.
Using this patch, model=i82559er at least works partially.
For full support, more eepro100 patches are needed
(will follow later, can be fetched from ar7 branch
of QEMU).

* Fix PCI configuration for existing devices.
* Add initialisation code for missing devices.
* Remove function device_supports_eTxCB.

* Fix dump of statistical data. It now respects

* CU_SHOWSTATS, CU_DUMPSTATS now write a
completion value after the statistical data.

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.

The idea of using assert() for input validation is rather questionable.
Let's remove it from eepro100, so that guests need to find more interesting
ways if they want to crash qemu.
This patch replaces asserts that are directly dependent on guest-accessible
data by other means of error handling.
