Oops. I'm afraid I've messed the things up a bit... ;) I've seen this 
issue when I checked the fix for the dev_stop()->dev_start() issue in 
the LRO patch. To remind, u have noticed that I wasn't freeing the 
not-yet-completed RSC aggregations in ixgbe_rx_queue_release_mbufs(). So 
when I was verifying the fix I've noticed the issue with the flags above 
and fixed it. But I've put the fix in the PATCH3 v7 of LRO series 
instead of putting it here... ;) I think I'll have to respin both series 
again... Ufff.... :(

Sounds reasonable. Since we talk about it - could u, pls., explain to me 
why is all this padding needed the first place? I must say I don't 
exactly understand why is it needed at all... ;)

I don't understand what u mean here. If scattered_rx != 0 then if vector 
Rx preconditions are met then rx_pkt_burst will be set to a vector-ed 
version of the callback and if not - to the non-vectored one. It will be 
exactly one setting... What do I miss? ;)

Yes they could. Do u think it would be more readable then? What I mean 
here is that DPDK is full of ifdefs because there is a million of 
configuration macros in rte_config.h. So, IMHO it would be better to 
explicitly indicate when these stubs are going to be used. However I'm 
also against the #ifdef's in general and actually like your proposal. 
Pls., comment.

NP. Here I just followed the previous code style of this section. ;) I
