Pedro F. Giffuni 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.

* headers are not a multiple of longwords in size this forces
* the data to non-longword aligned. Since IP requires the
* data to be longword aligned, we need to copy it after it has
* been DMA'ed in our memory.
*
* Since we have to copy it anyways, we might as well as allocate
* dedicated receive space for the input. This allows to use a
* small receive buffer size and more ring entries to be able to
* better keep with a flood of tiny Ethernet packets.
*
* The receive space MUST ALWAYS be a multiple of the page size.
* And the number of receive descriptors multiplied by the size
* of the receive buffers must equal the receive space. This
* is so that we can manipulate the page tables so that even if a
* packet wraps around the end of the receive space, we can
* treat it as virtually contiguous.
*
* The above used to be true (the stupid restriction is still true)
* but we gone to directly DMA'ing into MBUFs (unless it's on an
* architecture which can't handle unaligned accesses) because with
* 100Mb/s cards the copying is just too much of a hit.
