Fix CID 113703 in the Coverity report on Linux.

ethtool stats names are limited to 32 bytes including a null
terminator.  Use strlcpy() to ensure that we will always include the
null terminator even if a source string becomes longer than this.

With some gcc versions & optimisations, the compiler will warn that
'depth' in efx_filter_insert_filter() may be used without being
initialised, although this is not the case.

This is related to inlining of efx_filter_search(), which only has
one caller since commit 8db182f4
('sfc: Remove now-unused filter function').

Shut the compiler up by initialising it to 0.

If the user hasn't actually installed any custom rules, or fiddled
with the default ones, don't go through the whole FIB rules layer.

It's just pure overhead.

Instead do what we do with CONFIG_IP_MULTIPLE_TABLES disabled, check
the individual tables by hand, one by one.

Also, move fib_num_tclassid_users into the ipv4 network namespace.

git commit 97cac082 (ipv6: Store route neighbour in rt6_info struct)
added a neighbour pointer to rt6_info. Currently we don't initialize
this pointer at allocation time. We assume this pointer to be valid
if it is not a null pointer, so initialize it on allocation.

This reverts the commit cdf49c28 which
replaces lowpan '.ndo_set_mac_address' method by ethernet's one.

Accorind to the IEEE 802.15.4 standard, device has 8-byte length address,
so this hook loses the last 2 bytes which may rise a compatibility problems
with other IEEE 802.15.4 standard implementations.
