4650ed44c1 net/sfc: support MCDI proxy
The patch is to add support for MCDI proxy which comes in
useful, particularly, while running over VF: few commands
will normally fail with EPERM, but in some cases the host
driver (i.e. running over the corresponding PF, typically,
within a hypervisor) may set itself as a proxy to conduct
authorization for the commands coming from VFs; these are
forwarded to the corresponding access control application
which may decline or approve authorization by replying to
the requests; all in all, the guest driver has to process
the replies forwarded back by the firmware MC in order to
give up gracefully (by setting return code which could be
understood by 'libefx') or re-issue the original commands

23c6d0dbac net/sfc/base: improve API to get supported filter matches
The previous API had various problems, including the length of the
caller provided buffer not being specified, no means being available
to discover how big the buffer needs to be, and a lack of clarity of
what the resulting list contains.

To improve it:
- add the buffer length as a parameter
- if the provided buffer is too short, fail with ENOSPC and return
  the required length
- ensure that the list contents are valid and add comments describing it

It is safe to change this API as, unsurprisingly, it has no users.

daa007afd0 net/sfc/base: split local MAC I/G back into separate flags
The flag EFX_FILTER_MATCH_LOC_MAC_IG to represent filtering on the
individual/group bit of the MAC address (with the two cases being
distinguished by the MAC address in the filter specification) was
introduced to mirror the Linux driver filtering code, but the
implementations are different enough anyway that it isn't of much
value.

Having separate flags for unknown unicast and multicast simplifies
the code and allows the set of flags to match those used by MCDI.

It will also makes it easier to report whether these filters are
supported.

In the MCDI definitions, the unknown multicast and unicast flags
have the values 0x40000000 and 0x80000000 respectively, and so using
the same values for simplicity requires 32 bits in the filter
specification to store the flags. This means the structure is now
a little bigger than 64 bytes, but filters are not often used on
critical paths so this shouldn't have much impact - on Linux they
are also bigger than they used to be.

feb9f680cd mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.
