c35524f0a1 Fix a serious problem in dp8390_write_mbuf(), noticed by Jason Thorpe: 
after we've written out the contents of the mbuf, increment the transmit
buffer offset by m->m_len.

a945a24322 Front-end to the dp8390 chip driver for the 3Com 3c503 Ethernet interface. 
Supports changing media with ifconfig's "media" directive.

This splits the 3c503 functionality out of the ISA "ed" driver, much the
same way NE2000 support was split out.

8ffb1f6b84 Nuke the special case of heldchange for reg 5. We don't use it for flow 
control any more, and the speed of changing DTR isn't really an issue.  Also,
the old code created a bug where zsparam() might have failed to set some
registers.

75dc31c41d Yet more changes imported from com driver: 
Change the interface to zs_hwiflow(); just have it use zst_rx_blocked.
Make zs_modem() a tiny bit faster.
Do RTS updates immediately; do not allow them to be held.

cb8172bce4 Chnage MACHINE_NONCONTIG implementation such that the message buffer is 
always located at the end of onboard RAM. This allows locore.s to zero
any offboard RAM to initialise the parity bit which most VMEbus RAM cards
have. Without this, many cards buserr on the first read access.
Thanks to Herb Peyerl for the idea.

8008239563 Rearrange open sequence to make sure we catch all line status changes. 
Make sure we turn on DTR and/or RTS as appropriate during open.
Rearrange close sequence so the tty is flushed before turning off interrupts.
Deal with `softcar' and the console device by silently asserting CLOCAL and
|HUPCL, as in com driver.
Do *not* fiddle with DTR when changing the line speed.
Make sure we update the tty's carrier status when CLOCAL or MDMBUF is changed.
Only change rr1 when we actually need to turn on or off TIE.

ba6431afae Incorporate a 4.4BSD-Lite workaround for a bug in cache invalidation. 
From   /sys/news3400/news3400/locore.s, with id
	@(#)locore.s	8.3 (Berkeley) 9/23/93

Kazumasa Utashiro notes that the pmax cacheflush routines don't work:
    #ifndef NOTDEF /* I don't know why Ralph's code doesn't work. KU:XXX */

It's because pmax hardware wries the COP0 bit to external branch
logic.  news3400s don't, and so the bc0f loop fails.  It will also
fail on some other models of pmax, but we dont' support them.
Surround the relevant framgents in locore_r200.S with "#ifdef pmax".

Longer-term,  the cacheflush entry in the locore callback may have
to be a  CPU baseboard-specific entry, not just CPU-version specific.
