Representor RX uses a NAPI context driven by a 'fake interrupt': when
the parent PF receives a packet destined for the representor, it adds
it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake
interrupt' is primed. The NAPI poll then pulls packets off this list
and feeds them to the stack with netif_receive_skb_list().
This scheme allows us to decouple representor RX from the parent PF's
RX fast-path.
This patch implements the 'top half', which builds an SKB, copies data
into it from the RX buffer (which can then be released), adds it to
the queue and fires the 'fake interrupt' if necessary.
