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.
number in the irq register. While there are other issues with these
variants, avoiding writing to it helps interrupt generation on at
least one card, and doesn't hurt on the others. Flag ISA attachment
as needing INT_NO_REG written, and don't update the PC Card attachment
(which will have the effect of not touching it for PC Cards).
Document this in a comment, and tweak one or two formatting nits while
I'm here.
- Add a mutex to the softc to protect the softc and device hardware.
- Use a private watchdog timer.
- Setup interrupt handler after ether_ifattach().
- Use bus_foo() rather than bus_space_foo() and remove bus space tag and
handle from softc.

struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

Use bus space rather than direct inb/outb. Minor style changes while
I'm here. Extremely preliminary support for siliconix ethernet cards
(but more work is required).
coming later this week. Mitsuru IWASAKI provided a patch to -mobile which
I used to make sure I was doing the right thing but only a small part of
the actual patch was used.
