8a2141f0e3 elink.[ch]: Move historic VCS tags after the license.

abbfe9e5d1 Move i386/isa/elink.[hc] to dev/ep.
The ep(4) driver is the only consumer of the two functions from
elink.c.  I removed the standalone module as well, and most likely,
the module metadata is not needed anywhere, but this is for later
cleanup.

5fe4723c70 Create a new ISA_PNP_INFO macro. Use this macro every where we have
ISA PNP card support (replace by hand version in if_ed). Move module
declarations to the end of some files. Fix PCCARD_PNP_INFO to use
nitems(). Remove some stale comments about pc98, turns out the comment
was simply wrong.

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.

f2e8ba3f76 Remove EISA support for ep driver. Left in place EISA strings that are
still relevant (ISA cards can still be in EISA mode, and we're still
ignoring those in the identify routine). Notes about cards in EISA
mode have been left in the manual since they aren't relevant to EISA
support, but instruct how to properly configure an ISA card in a mode
when it is in a ISA bus slot.

5625fe9246 Remove Micro Channel Architecture support. Of the commonly available
machines, only a few 486 machines that used it, and those haven't had
enough memory to run FreeBSD for quite some time (often limited to

block. Use it in all the PNP drivers to export either the current PNP

MODULE_PNP_INFO since it's the only one that matches on function

e89da24b3d Two refinements to the 3c1 support:
1) Flag it and only access that command on the 3c1
2) The TX PLL appears to power down when not in use, so we have to power
   it back up when we've been idle.  Do this at the start of ifstart.
   Otherwise we fall off the net.

52fcedff50 o Report ethernet status for at least 10BaseT media. Since I don't
have other media to test against, I've left that media reporting
  unchanged.
o Enable the TX_PLL when we enable TX.  This is harmless on most
  cards, but required to get the 3c1 CF card working.  Power savings
  could be had by managing this better, but for now it gets my card
  working.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

880266e041 Minor cleanup of ep driver and pccard attachment:
o Grab the MAC address out of the CIS if the card has the special
  3Com 0x88 tuple.  Most 3Com cards don't have this tuple, but we
  prefer it to the eeprom since it only appears to be present when
  the eeprom doesn't have the info.  So far, I've only observed this
  on my 3C362 and 3C362B cards, but the NetBSD driver implies that
  the 3C362C also has this tuple, and that some 3C574 cards do too (none
  of mine do).  ep_pccard_mac was written after looking at the NetBSD
  code.
o Store the enet addr in the softc for this device, so we can use the
  overridden MAC to set the station address.
o Create a routine to set the station address and use it where we need it.
o setup the cmd shitfs and such before we call ep_alloc(), and remove
  setting up the cmd shift value there.  It initializes to 0, and those
  attachments that need to frob it do so before calling ep_alloc.
o Remove some obsolete comments
o No longer a need to export ep_get_macaddr, so make it static
o ep_alloc already grabs the EEPROM id, so we don't need to grab it again
  in ep_pccard_attach.
o eliminate unit, it isn't needed, fix some printfs to be device_printf
  instead.

cdcf928a55 Add a chipset field to the lookup. Use this chipset type to determine
which command to use to read the eeprom and which devices have an MII.
Simplify code by no longer using the OLDCARD compat rouintes (I don't
know if this breaks OLDCARD on pc98 or not, but OLDCARD on pc98 days
are numbered, I hope).  This also removes a number of kludges that we
had before because they are OBE.  Add a convenience routine to lookup
the device to avoid many casts in many places.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
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.
