allow the user to set and use the internal baud rate generator
fix the transmission ring logic to support more than 1 frame per interrupt
add autodetection of the base clock frequency.
cleanup the receive ring logic
support dynamically resizing the low-water mark on the fifo in response
to buffer underruns on transmit.
This is not strictly necessary, as
- at least for the Ricoh chip in the A3000 and A4000, as those chips' Y10
registers happily continue to count up from 0xA if manually incremented
past 0x9.
- the Amiga ROMs and "setclock" commands seem to interpret 0xA 0x? like
200?, etc.
However,
- the Amiga setclock writes the modulo 10 value into the chips
- the chip docs of both chips, including the Y2K information of their
manufacturers, only refer to the range 0-9
- the chips increment from 9 to 0
So we better conform to this, to avoid unpleasant surprises.
this allows you to disable/enable ICMPv6 node information query/reply
processing (which tells remote end the gethostname(3) setting, interface
addresses on the node, and some other things - documented in
draft-ietf-ipngwg-icmp-name-lookup* or something alike).
to test it, try ping6 -w ::1 with nodeinfo=0 and nodeinfo=1.
(sync with kame change)
preserve enough of the state of the PCIC to keep it interrupting on
card insertion/removal..
Add a power hook to notice if the CSC_INTR device register is zeroed
on resume, and if so, reset it to a sane value.
sys_write().
netbsd32_getfsstat() cannot just copyin()/copyout(), convert the structures,
and call sys_getffstat(). sys_getffstat() wants to do its own
copyin()/copyout(). So we need to implent the whole of sys_getffstat()
in netbsd32_getfsstat().
remove ffs()
add bzero that uses block store insns
save %gsr to fpstate
revert to physical accesses for pmap_zero_page so we don't
have conflicting page mappings
general cleanup.
