naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Add a real PCI front-end for PCnet-PCI Ethernet cards.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.

(and only tested on) Intel Etherexpress PRO. Should work on any i82595 ISA
board which uses an EEPROM for config information; NETBLKID not yet supported.
TODO: change to BUS interface, add multicast support.
Use the i/o handle for the `delay port' exported from the parent
ISA bus, rather than the totally bogus combination of [ioh, 0x84].
Also, fix a bug apparently introduced when the -Wall changes were checked
in which, under most circumstances, would cause a 16-bit WD8013EP to
be mis-identified as an 8-bit WD8003EP.
For the ISA probe, implement a way to keep track of which ISA busses
have been through an ep_isa probe; the static variable that was used
before didn't scale.
In elink_reset(), since some machines may have more than one ISA bus,
implement a way of keeping track of which ISA bus has received an
elink_reset(); The static variable which was used previously didn't
scale.
bus-independent core driver. Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
chip-independent clock code. 'clock' has been renamed 'mcclock' 'clock'
has been renamed 'mcclock' (since it's a driver for that particular
clock, and since eventually there may be another clock chip driver),
and now attaches via seperate match/attach functions to both TC and ISA.
This removes a whole lot of #ifdefs...
'cflag' for the console. Normally set to TTYDEF_CFLAG, may be
overridden by machine-dependent console attachment code, as necessary.
(Alpha uses it to set cs8 -parenb.) Files including comvar.h now
need to include <sys/termios.h>, because comconscflag is of type
tcflag_t.
tech-kern (?)), to get the IPL_* and IST_* types. pass the machine-dependent
cookie given at attach time on to sub-devices, so they can use it to access
the interrupt functions properly.
the isa_chipset_tag_t type, and to define or prototype:
isa_attach_hook()
isa_intr_establish()
isa_intr_disestablish()
i.e. the machine-dependent functions to be used my MI ISA code.
Remove prototypes for the latter two functions from this file.
the bus is configured, interrupts are handled, etc. machine-dependent
header (machine/eisa/eisa_machdep.h) defines eisa_chipset_tag_t and
eisa_intr_handle_t types, and the following functions:
eisa_attach_hook()
eisa_maxslots()
eisa_intr_map()
eisa_intr_string()
eisa_intr_establish()
eisa_intr_disestablish()
Don't define the interrupt establish/disestablish functions directly
in terms of the ISA functions any more (on some wacked out systems,
there can be a difference).
* Add an ACB_RESET flag, so that a BUS DEVICE RESET can be queued within the
driver.
* If ACB_ABORT or ACB_RESET is set during reselection, schedule a message and
assert ATN.
* Optimize aic_datain_pio(), aic_dataout_pio() and aicintr() somewhat.
* Schedule a timeout only when we select the target, so that commands can't
time out prematurely.
influence from the old driver (written by Stefan Grefen) and from
an autochanger driver written by the Systems Programming Group at the
University of Utah Computer Science Department (currently residing
in src/sys/arch/hp300/dev/ac.c).
1) If we get an unexpected disconnect, issue a REQUEST SENSE, as recommended
by the SCSI-2 spec. If the target created a contingent allegiance condition,
this will clear it. Also, if it happened while sending a SDTR or WDTR message,
disable negotiation for that target.
2) Since some lame devices still don't deal correctly, make sure we deassert
ATN if our last message out is interrupted. If we get a MESSAGE PARITY ERROR,
we'll reassert ATN anyway. This should ensure that we never have to send a
MESSAGE NO OPERATION.
3) Set AIC_ABORTING only when actually sending a BUS DEVICE RESET or ABORT,
so we get better error detection.
4) Other internal reorganization of no consequence.
- Remove unnecessary prototypes
- Fix ioctl arguments
- Don't use kprintf(...TO_LOG...); directly. This does not set the log
priority, and uses priority of the previous message. Use log() with %:
