Subject: Re: [PATCH] tg3 intr masking update

Additional note about this change,

The NAPI docs mention specific areas where races may occur, and 
coincedentally so do the tg3 docs.  The tg3 docs suggest to me that in 
tg3_poll, after we unmask ints, we should
* flush the MMIO write
* check the status block for updates again
* tell tg3 to deliver to us an artificial interrupt just in case we 
raced [IMO preferred versus simply returning 'not-done' in tg3_poll retval]

But this is just a theory and not tested yet...
