The current deprecated list is: ae, bm, cs, de, dme, ed, ep, ex, fe,
pcn, sf, sn, tl, tx, txp, vx, wb, xe
The list as refined as part of FCP-0101. Per the FCP, devices may be
removed from the deprecation list if enough users are found or they are
converted to iflib.

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.

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.
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.
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.
support. Fix a comment block that's shared with both vx and ep. Remove
obsolete refernce to statically compiling a kernel with a fixed number
of vx devices. Have not removed EISA from the title of the document
the register definitions were originally derived from (though no doubt
more recent docments were also consulted).

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

queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

if_watchdog and if_timer.
- Fix some issues in detach for sn(4), ste(4), and ti(4). Primarily this
means calling ether_ifdetach() before anything else.
# My reading of the docs suggests this can only happen on 10Base5 and

# adequately since I have nothing but 10BaseT, etc here.
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.
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.
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.
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.
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;

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.

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.

o Rename get_e() to ep_get_e() to avoid namespace pollution.
