[PATCH 1/2] net: thunderx: Set recevie buffer page usage count in bulk

Hi David,

quoted

you create a window of time during which the consumer
can release the page and prematurely free it.

Okay, but here the consumer i.e HW is notified only after page count
is incremented.
For example if you check 'nicvf_refill_rbdr' fn() only after receive
buffer ring is
refilled with buffers, doorbell is issued to hardware to start using
the new buffers.

So

@@ -241,6 +254,8 @@ refill:
                new_rb++;
        }

+       nicvf_get_page(nic);
+

calling 'nicvf_get_page' before issuing doorbell ensures page ref
count is properly
set before hw/consumer can use the buffers.

Thanks,
Sunil.
