pk 547d95a029 Remove esp FLUSH when residual bytes are present in FIFO, the ncr53c9x 
driver will flush when necessary. Doing the FLUSH here interferes
with DMA-enabled target selection.

pk 2357b53997 Avoid race for the chip's interrupt pending status bits in zscnputc() 
by introducing a single-character queue to defer kernel console output
until the transmitter interrupt handler runs.

mrg bb07095632 as per discussion with torek, allow TC=1. also add option 
to allow TC=0.  the zilog documentation says not to allow
TC=0 -- however, i tested this and it "does work", as far
as i could tell, so, allow this use if so desired.

pk 27b2f0ec7c Fix a `new-ARP' pasto. 1997-03-15 22:13:55 +00:00
is 07b064e02e New ARP system, supports IPv4 over any hardware link. 
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

cjs ca5f101ba7 Remove code that stops transfers of >63K. The Sun 4 doesn't have this 
limitation, and minphys() is supposed to catch this on other architectures.

cgd e36a5ca4de change microcode array definitions from "unsigned short" to the more 
correct u_int16_t, and remove bogus casts that the old definition
required.

more encodings, and make it device-independent.  From Lennart Augustsson, in
PR kern/3305.

PROM does not provide a parent/child relationship.

gwr 2de163471e Minimal changes to adapt to removal of NCR5380_PERMIT_RESELECT. 
This driver should be updated to allow per-target control over
disconnect/reselect, but I will leave that to the port masters.

pk 3cb63476b7 One control block per target is insufficient if you have a full complement
