Several months back I reported a bug in the CS8900A driver, that it could
not properly handle odd length pbufs. For my project, I was able to solve
this problem. My fix will not fix the bug in the CVS code however, since
my driver assumes an 8 bit interface to the CS8900 chip. If you are using
the CS8900 chip, you will need to fix this bug before you can transmit odd
len pbufs. Note this bug is related to the number of bytes in each pbuf,
which is not necessarily related to the packet size.
I would appreciate a link be added from the lwIP pages to my project when
someone has a spare moment. The URL is:
