Subject: [Intel-wired-lan] [PATCH] fm10k: Limit dma sync of RX buffers to actual packet size

From: "Peterson, Scott D" <scott.d.peterson at intel.com>

On packet RX, we perform a dma sync for cpu before passing the packet up.  Here we limit that sync to the actual length of the incoming packet, rather than always syncing the entire buffer.

Testing Hints:
Verify traffic is still passed correctly with the same or better performance as before this patch
