Hi,
this is the second version of a series of patches for eepro100 which mainly
fix endianness issues and enhance register access. There was a bug report
on qemu-devel recently which is fixed by these enhancements, see
http://lists.nongnu.org/archive/html/qemu-devel/2011-03/msg02109.html.
Changes in v2:
* The 2nd patch is new.
* Patches are sorted in a different order. The first 4 patches and the
rest are independent, so it's possible to apply parts of the series.
* The endianness patch was updated to address the feedback which I received.
I still use local functions to access physical memory - mainly because
I want to use cpu_physical_memory_read / cpu_physical_memory_write as long
as I am not sure whether the alignment requirements for the suggested
open coded variant are met.
The prefix is e100 - shorter and more up-to-date than eepro100.
When I started this device emulation, linux still used a module called
eepro100. Today, the only linux module is called e100. So my final goal
is renaming all eepro100 to e100.
I did not change the patch which adds padding to short received frames,
because I'd like to keep the preprocessor statement (CONFIG_PAD_RECEIVED_FRAMES)
as some kind of documentation (even if QEMU's network code won't be modified
in the near future to fully support a real ethernet emulation).
Kind regards,
Stefan W.
