iavf uses the netdev->lock already to protect shapers.
In an upcoming series we'll try to protect NAPI instances
with netdev->lock.
We need to modify the protection a bit. All NAPI related
calls in the driver need to be consistently under the lock.
This will allow us to easily switch to a "we alre
Move the call to skb_record_rx_queue in idpf_rx_process_skb_fields()
so that RX queue is recorded for RSC packets too.

Handle rsc packet with a single segment same as a multi
segment rsc packet so that CHECKSUM_PARTIAL is set in the
skb->ip_summed field. The current code is passing CHECKSUM_NONE
resulting in TCP GRO layer doing checksum in SW and hiding the
issue. This will fail when using dmabufs as payload buffer

This patchset fix a possible time window problem for page_pool and
the dma API misuse problem as mentioned in [1], and try to avoid the
overhead of the fixing using some optimization.
