Some of the tracing seems to be remaining traces for basic driver
development. They can be removed now, as they cause noisy printouts.

1. modify bd_status from u32 to u16 in function hdlc_rx_done,
because bd_status register is 16bits
2. write bd_length register before writing bd_status register

napi_complete_done() allows to opt-in for gro_flush_timeout,
added back in linux-3.19, commit 3b47d30396
("net: gro: add a per device gro flush timer")
This allows for more efficient GRO aggregation without
sacrifying latencies.

Size used with 'dma_alloc_coherent()' and 'dma_free_coherent()' should be
consistent.
Here, the size of a pointer is used in dma_alloc... and the size of the
pointed structure is used in dma_free...
This has been spotted with coccinelle, using the following script:
////////////////////
@r@
expression x0, x1, y0, y1, z0, z1, t0, t1, ret;
@@
* ret = dma_alloc_coherent(x0, y0, z0, t0);
...
* dma_free_coherent(x1, y1, ret, t1);
@script:python@
y0 << r.y0;
y1 << r.y1;
@@
if y1.find(y0) == -1:
print "WARNING: sizes look different: '%s' vs '%s'" % (y0, y1)
