The free path previously had a bug that would cause it to skip the free bucket

These changes made the bucket handling code much cleaner and removed quite a

The changes to rlphy.c are based largely on the patch from PR 30836,

Also updated if_rl.c to allow the rlphy driver to read the RL_MEDIASTAT

interrupts. This is a bit harder than it needs to be because there's
more than one way to generate link attentions, at least one of which
does not work on the BCM5700, but does on the 5701.
For the 5701, we can safely use the 'link changed' bit in the status
block, and we enable link change attentions in the mac event register.
For the 5700, we have to use MII interrupts, which require checking
the MAC status register rather than the status block. This requires
doing an extra register access on each interrupt which I'd prefer to
avoid, but them's the breaks. Testing with both a 3c996-T and 3c996B-T
shows that we do in fact detect the link going up and down properly
on cable insertions/disconnections.
Also, avoid twiddling the autopoll enable bit in the MI mode register
when doing a PHY read. I think this coupled with the other changes
will stop the interrupt storms Paul Saab has been harassing me about.
Manually setting the link to 100baseTX full duplex seems to work ok
for me. (I'm typing over the 3c996B-T right now.)
Lastly, teach the driver how to recognize a 3c996B-SX by checking
the hardware config word in the EEPROM in order to detect the media.
We attach 5701 fiber cards correctly now, but I haven't verified that
they send/receive packets yet since I don't have a second fiber
interface at home. (I know that fiber 5700 cards work, so I'm
keeping my fingers crossed.)
This driver was written by Myson and is made available

I will commit it soon.
Myson have their own chip design based on the DEC 214xx family but
with several differences. Myson sells this chip to several
EOMs in teh Chinese area so there may be many noname brand cards
that respond to this driver. Myson will be supplying a list
of some of these.

Be more careful when setting the alternate interface so we don't
end up with nothing set at all if it fails.

As a safety, check that the controller is not suspended when we get
an interrupt.

Add a delay before reading the number of ports from the controller to
avoid getting 0 from it.

A first stab at support for isochronous transfers.
===================================================================
MI, not required to be a fixed size, and used in multiple headers.
This will grow in time, as more things move here from <sys/types.h>
and <machine/ansi.h>.
o Add missing type definitions (uint16_t and uint32_t) to
<arpa/inet.h> and <netinet/in.h>.
o Reduce pollution in <sys/types.h> by using `#if _FOO_T_DECLARED'
widgets to avoid including <sys/stdint.h>.
o Add some missing type definitions to <unistd.h> and note the ones
that still need to be added.
o Make use of <sys/_types.h> primitives in <grp.h> and <sys/types.h>.

dump the trace buffer feasible.
- Remove KTR_EXTEND. This changes the format of the trace entries when
activated, making writing a userland tool which is not tied to a specific
kernel configuration difficult.
- Use get_cyclecount() for timestamps. nanotime() is much too heavy weight
and requires recursion protection due to ktr traces occuring as a result
of ktr traces. KTR_VERBOSE may still require recursion protection, which
is now conditional on it.
- Allow KTR_CPU to be overridden by MD code. This is so that it is possible
to trace early in startup before pcpu and/or curthread are setup.
- Add a version number for the ktr interface. A userland tool can check this
to detect mismatches.
- Use an array for the parameters to make decoding in userland easier.
- Add file and line recording to the non-extended traces now that the extended
version is no more.
These changes will break gdb macros to decode the extended version of the
trace buffer which are floating around. Users of these macros should either
use the show ktr command in ddb, or use the userland utility which can be run
on a core dump.

Tested on: i386, sparc64
Caveats:
The new savecore program is not complete in the sense that it emulates
enough of the old savecores features to do the job, but implements none
of the options yet.
I would appreciate if a userland hacker could help me out getting savecore
to do what we want it to do from a users point of view, compression,
email-notification, space reservation etc etc. (send me email if
you are interested).
Currently, savecore will scan all devices marked as "swap" or "dump" in
/etc/fstab _or_ any devices specified on the command-line.
All architectures but i386 lack an implementation of dumpsys(), but
looking at the i386 version it should be trivial for anybody familiar
with the platform(s) to provide this function.
Documentation is quite sparse at this time, more to come.
Details:
ATA and SCSI drivers should work as the dump formatting code has been
removed. The IDA, TWE and AAC have not yet been converted.
Dumpon now opens the device and uses ioctl(DIOCGKERNELDUMP) to set
the device as dumpdev. To implement the "off" argument, /dev/null
is used as the device.
Savecore will fail if handed any options since they are not (yet)
implemented. All devices marked "dump" or "swap" in /etc/fstab
will be scanned and dumps found will be saved to diskfiles
named from the MD5 hash of the header record. The header record
is dumped in readable format in the .info file. The kernel
is not saved. Only complete dumps will be saved.
All maintainer rights for this code are disclaimed: feel free to
improve and extend.

have ripped all the i386 specific formatting code from their
dump routines. Due to the potential for trashing disks, I did
not want to do this "blind".
This design is my best effort and it is quite likely that people more used
to kernel dumps may want to change this subsequently so two levels of
version numbers are provided: one for the common header and one per
architecture.
