718cf2ccb9 sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

e3ef7bb216 sfxge(4): avoid unnecessary mbuf data prefetch
Unnecessary prefetch just loads HW prefetcher and displaces other
cache entries (which could be really useful).

If we parse mbuf for TSO early and use firmware-assisted TSO, we do not
expect mbuf data access when we compose firmware-assisted TSO (v1 or v2)
option descriptors.  If packet header needs to be linearized or finally
FATSO cannot be used because of, for example, too big header, we do not
care about a bit more performance degradation because of prefetch
absence (it is better to optimize more common case).

63492ab8be sfxge(4): fix efx_filter_supported_filters API
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 fix 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, unsuprisingly, it has no users.

a85ebf7757 sfxge(4): split EFX_FILTER_MATCH_LOC_MAC_IG 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
distingusished 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.
