i40e/i40evf: Limit DMA sync of RX buffers to actual packet size
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.

nder `pch->lock'. Second, I have removed locking from `pl330_request_channel' and `pl330_release_channel' functions. Function `pl330_request_channel' is only called from `pl330_alloc_chan_resources', so the lock is already held. Function `pl330_release_channel' is called from `pl330_free_chan_resources', which already holds the lock, and from `pl330_del'. Function `pl330_del' is called in an error path of `pl330_probe' and at the end of `pl330_remove', but I assume that there cannot be concurrent accesses to the protected data at those points.
