when grepping for JOBS. The recent style cleanup replaced the space with
a tab and broke job control detection. Little edits, disastrous consequences.

X-MFC when: in about 5 weeks with the other sh arithmetic fixes.
We simply use the detected FIFO size to determine whether we have
a post 16550 UART or not. The support lacks proper serialization of
hardware access for now.
pmap_extract_and_hold(). Note, however, that GIANT_REQUIRED should not be
removed until all platforms fully implement the "prot" parameter to
pmap_extract_and_hold().

fixes a longstanding issue WRT resetting the chip after startup- it
would fail if we were connected as an F-port to a switch. If we
were connected as an F-port, we got assigned a hard loop ID of 255,
which is really a bogus loop id. Then when we turned around to
reset ourselves, the firmware would reject the ICB_INIT request
because the loop id was bogus. *sputter*
Minor fixlet from somebody in NetBSD with too much time on their
hands (dma -> DMA).
the "compatible" property too in the ns8250 case. This gets the serial
console to work on Blade 100s, where the device name is just "serial".

only code-change is to add a "next_time" parameter to both routines (and
that is not used yet). A later update will make "next_time" more useful.

Second (PPS) timing interface. The support is non-optional and by
default uses the DCD line signal as the pulse input. A compile-time
option (UART_PPS_ON_CTS) can be used to have uart(4) use the CTS line
signal.
Include <sys/timepps.h> in uart_bus.h to avoid having to add the
inclusion of that header in all source files.

This commit puts the relevant code snippets under #ifdef GONE_IN_5
(rather than #ifndef BURN_BRIDGES) thereby disabling the code now.
The code wil be entirely removed before 5.2 unless we find reasons
why this would be a bad idea.
Approach suggested by: imp
seems to be necessary for the 8139C+ under certain circumstances, and
doesn't appear to hurt the other chips. (In the failure case, the
packet would be sent through the TX DMA ring but not get echoed
back. I suspect this has something to do with the link state changing
unexpectedly.)
autoload and then copying the contends of the station address
registers. For some reason, reading the EEPROM on the 8169S doesn't
work right. This gets around the problem, and allows us to read
the station address correctly on the 8169S.
- Insert a delay after initiating packet transmition in re_diag() to
allow lots of time for the frame to echo back to the host, and wait
for both the 'RX complete' and 'timeout expired' bits in the ISR
register to be set.
- Deal more intelligently with the fact that the frame length
field in the RX descriptor is a different width on the 8139C+
than it is on the 8169/8169S/8110S
- For the 8169, you have to set bit 17 in the TX config register
to enter digital loopback mode, but for the 8139C+, you have to
set both bits 17 and 18. Take this into account so that re_diag()
works properly for both types of chips.
