My best guess is to check your buffer descriptor settings.  Are you setting
the L and W bits in your single BD?  I assume you're polling the BD to
determine when the frame has been sent; are there any errors?  In particular,
is the Retry Count field non-zero?  Is your polling code inadvertently writing
to the BD (rather than just reading it) and setting the R bit again?
