Since you explicitly call them 'bug fixes'... I suppose the last patch
in the latest series (enabling the various offloads by default) isn't a
bug fix and should be held back for net-next.

I think I can live with pushing the rest for the net tree. Just to
recap, the series is:

      8139cp: Do not re-enable RX interrupts in cp_tx_timeout()
      8139cp: Fix tx_queued debug message to print correct slot numbers
      8139cp: Fix TSO/scatter-gather descriptor setup
      8139cp: Reduce duplicate csum/tso code in cp_start_xmit()
      8139cp: Fix DMA unmapping of transmitted buffers
      8139cp: Dump contents of descriptor ring on TX timeout
      8139cp: Enable offload features by default

The penultimate patch is also not strictly a bug fix, but it's only
adding additional diagnostics to a code path which was already broken 
until I fixed it anyway, so I can live with that in net although I'll
also be happy if you want to defer it.

The fourth patch which removes the three duplicate versions of the
csum/tso checks might also be deferrable but really, it's *also*
fixing the failure mode when we see an inappropriate CHECKSUM_PARTIAL
packet, and it's touching a code path which I've *also* fixed in this
patch set. So it might as well stay.

I can shuffle things around if you disagree, but assuming Francois
concurs I'd suggest merging patches 1-6 (or just pulling from
git://git.infradead.org/users/dwmw2/linux-8139cp.git fixes-only)
and then I'll resubmit the last patch some time later, after you
next pull net into net-next.

Otherwise, please let me know if/how you'd like me to reorganise it.
