Jakub Kicinski says:

====================
net: remove non-Ethernet drivers using virt_to_bus()

Networking is currently the main offender in using virt_to_bus().
Frankly all the drivers which use it are super old and unlikely
to be used today. They are just an ongoing maintenance burden.

In other words this series is using virt_to_bus() as an excuse
to shed some old stuff. Having done the tree-wide dev_addr_set()
conversion recently I have limited sympathy for carrying dead
code.

Obviously please scream if any of these drivers _is_ in fact
still being used. Otherwise let's take the chance, we can always
apologize and revert if users show up later.

Also I should say thanks to everyone who contributed to this code!
The work continues to be appreciated although realistically in more
of a "history book" fashion...

-	depends on VIRT_TO_BUS
-	help
-	  This is a driver for high-speed SCC boards, i.e. those supporting
-	  DMA on one port. You usually use those boards to connect your
-	  computer to an amateur radio modem (such as the WA4DSY 56kbps
-	  modem), in order to send and receive AX.25 packet radio network
-	  traffic.
-
-	  Currently, this driver supports Ottawa PI/PI2, Paccomm/Gracilis
-	  PackeTwin, and S5SCC/DMA boards. They are detected automatically.
-	  If you have one of these cards, say Y here and read the AX25-HOWTO,
-	  available from <http://www.tldp.org/docs.html#howto>.
-
-	  This driver can operate multiple boards simultaneously. If you
-	  compile it as a module (by saying M instead of Y), it will be called
-	  dmascc. If you don't pass any parameter to the driver, all
-	  possible I/O addresses are probed. This could irritate other devices
-	  that are currently not in use. You may specify the list of addresses
-	  to be probed by "dmascc.io=addr1,addr2,..." (when compiled into the
-	  kernel image) or "io=addr1,addr2,..." (when loaded as a module). The
-	  network interfaces will be called dmascc0 and dmascc1 for the board
-	  detected first, dmascc2 and dmascc3 for the second one, and so on.
-
-	  Before you configure each interface with ifconfig, you MUST set
-	  certain parameters, such as channel access timing, clock mode, and
-	  DMA channel. This is accomplished with a small utility program,
-	  dmascc_cfg, available at
-	  <http://www.linux-ax25.org/wiki/Ax25-tools>. Please be sure to
-	  get at least version 1.27 of dmascc_cfg, as older versions will not
-	  work with the current driver.
