net: hamradio: remove support for DMA SCC devices 



Another incarnation of Z8530, looks like? Again, no real changes
in the git history, and it needs VIRT_TO_BUS. Unlikely to have
users, let's spend less time refactoring dead code...

	  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.
