I'm new to this, so please don't flame me if I've done something wrong :)
Earlier this year, I purchased a Diamond PCI card and set it up to work with
Linux. To get the card to work in HomePNA mode, I had to copy over some code
from the Linux 2.2.18 pcnet32.c to the Linux 2.6 pcnet32.c. I noticed in the
comment regarding this card that "there probably should be some sort of
module option to select the mode by which the card should operate," so I
wrote one, attached as a patch. The option is called pcnet32_homepna. I
read SubmittingPatches and CodingStyle, so I think it's formatted correctly
and all. It works on my computer, and unfortunately I'm the only one in my
family with this specific card, so I can't test it anywhere else.
Here's the command to invoke it after it's patched:
modprobe pcnet32 pcnet32_homepna=1
for HomePNA, or
modprobe pcnet32
for standard Ethernet.
I made it go into standard ethernet by default because, despite comments to
the contrary, this is the default behavior I observed in Linux 2.4 and 2.6.
The patch is against Linux 2.6.6.
Please Cc me as I am not on this list if you make a decision about this patch.
