Converting fallthrough comments to fallthrough; creates warnings
in this code when compiled with gcc.
This code is overly complicated and reads rather better with a
little refactoring and no fallthrough uses at all.
Remove the fallthrough comments and simplify the written source
code while reducing the object code size.
Consolidate duplicated switch/case blocks for IPV4 and IPV6.

It's a resource, not a parameter, so we can't copy it into the new
channel's TX queues, otherwise aliasing will lead to resource-
management bugs if the channel is subsequently torn down without
being initialised.
Before the Fixes:-tagged commit there was a similar bug with
tsoh_page, but I'm not sure it's worth doing another fix for such
old kernels.

We now ignore the "completion" event when using tx queue timestamping,
and only pay attention to the two (high and low) timestamp events. The
NIC will send a pair of timestamp events for every packet transmitted.
The current firmware may merge the completion events, and it is possible
that future versions may reorder the completion and timestamp events.
As such the completion event is not useful.
Without this patch in place a merged completion event on a queue with
timestamping will cause a "spurious TX completion" error. This affects
SFN8000-series adapters.

We can't just use the top bits of the last sync event as they could be
off-by-one every 65,536 seconds, giving an error in reconstruction of
65,536 seconds.
This patch uses the difference in the bottom 16 bits (mod 2^16) to
calculate an offset that needs to be applied to the last sync event to
get to the current time.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.
