See gcc info pages: "Macros with a Variable Number of Arguments."
The ISO-C stadanrd doesn't allow varargs macros to get zero or more
arguments. So this fixes the problem using the gcc extension.

A standard-compliant alternative would be to have "fmt" included in
the variadic part, like this:

  #define assert(cond, ...) \
        if (CONFIG_HAS_ASSERT && !(cond)) \
                __assert(__func__, __LINE__, 1 /* forever */, __VA_ARGS__)

But the reader wouldn't  now it's a fmt+args.

By default, the bit is zero (masked), which means that PPS signal output is masked
when the link status is not ok. This is useful to pervent spurious PPS when in
SLAVE mode and the link goes down.

When the bit is set, then a PPS is always generated (as long as the PPS valid bit
in the ESCR register is set). This is useful in master mode.

By making struct wr_minic non static it is possible for mini SNMP to get RX/TX
counters' values directly from the memory instead of writing a separate
function that will call minic_get_stats. Avoiding extra function saves about

EE_BASE_INIT did not include t24p and sfpcount. Due to that init script was overwriten
by adding the 4th SFP. Limit number of SFP in the database to 3. Keep init script's
starting address unchanged for backward compatibility.
SDB is not affected. Use maximum 4 SFPs in the database when SDB is used.

This allows several functions to be static in the files where they
are defined. See temperature.c for an example.

But mainly, the idea is allowing ease addition of features (likely
Kconfig'd ones) for specific WR users, without any modification to the
main function and other generic code.  This will happen soon for snmp,
for example.

We may push this a little further, by moving all shell stuff into
shell.c, the ptp task within ppsi itself, and so on. But now my time
is over.

This costs anoter 220 bytes in the binary, becuase we now loop among
all temperature providers in order to return data to the caller.

The providers are clustered using an ELF section.

This commit adds data structures, methods and a process to manage
temperature.  Currently the only temperature being read is the onewire
thermometer, so there is no difference with what we had before.
The cost is 1.1 kB in binary size.

Well, there is a difference: only the stat engine was reading
temperature, while now the thermometer is read continuously (every 15
seconds, or another Kconfig-urable interval).  This takes quite some
CPU time (18.5ms per polling loop, but allows any user to read
temperature (using the API we now provide) without re-reading the
onewire bus.

The real aim of this is monitoring a board-specific set of sensors,
as implemented and show in the next commit.

Also, this changes how to mac address is retrieved in patching pfilter
rules. I'd better use format_mac(get_mac) for the verbose message,
so get_mac is also the source for patching the rules.

WARNING: wr_switch_defconfig doesn't build, this is fixed in next commit

Unfortunately this commit makes the internal communication between
minic and lan asymmetric: on receive the tag is discarded (and the
longer header falls into the payload) while on transmit it must be
provided by lan.c.

The reason is that on receive we can trim 4 bytes from the payload,
but on send we can't add 4 bytes without a memmove.  The functions
receive pointers to two different header structures, so hopefully
user errors will be signalled by the compiler.

Still, users interact with net.c, which hides vlan completely from
them.

Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

We used to have "struct ethhdr" local in net.c, passing "void *hdr" to
minic.  We exports the structure to an header so to use it in
communicating with the minic.  Unfortunaltey, ethhdr is defined elsewhere
too, so we'd better rename to wr_ethhdr.

This is a step towards the introduction of vlans, but has no technical
effect by itself.
