Dave,

Here are two more late-bloomers for 2.6.35.  Both are tiny and isolated,
and they fix documented regression BUGs as indicated in their commit logs.

The one from me changes a netif_rx to a netif_rx_ni -- the execution
path is in process context, coming from userland.  The bug reporter
confirmed that it addressed the problem he reported.

The one from Ming Lei has been in net-next-2.6 for a while already.
More recently, someone posted an identical patch indicated it addressed
the BUG as reported in the cited LKML thread.

I think it would be best to get these into 2.6.35 if at all possible.
Please let me know if there are problems!

Thanks,

John
