RX Buffers are refilled in chunks of 16 at a time before notifying the
hardware with a register write. This can cause several writes to take
place in a given napi poll call. This change causes the write to take place
only once at the end of the call.

Instead of taking/giving the hw semaphore repeatedly when iterating over
several frame to queue route settings, we have the caller hold it until
all are done.
This reduces PCI bus chatter and possible waits.

The large receive buffer queue is not properly tracking the current
index in the case where an early exit occurs. This can happen when a
page alloc or dma mapping fails. If this occurs the queue will get
out of sync and invalid indexes can be written to the hardware.

Shadow registers are consistent memory locations to which the chip
echos ring indexes in little endian format. These values need to
be endian swapped before referencing.
Note:
The register pointer declaration uses the volatile modifier which
causes warnings in checkpatch.
Per Documentation/volatile-considered-harmful.txt:
- Pointers to data structures in coherent memory which might be modified
by I/O devices can, sometimes, legitimately be volatile. A ring buffer
used by a network adapter, where that adapter changes pointers to
indicate which descriptors have been processed, is an example of this
type of situation.
