fail with "bind: address already in use". This problem was reported
to the freebsd-stable@ mailing list on Feb. 19 under the subject
heading "statd/lockd startup failure" by george+freebsd at m5p dot com.
The problem is that the first combination of {udp,tcp X ipv4,ipv6}
would select a port# dynamically, but one of the other three combinations
would have that port# already in use. The patch is somewhat involved
because it was requested by dougb@ that the four combinations use the
same port# wherever possible. The patch splits the create_service()
function into two functions. The first goes as far as bind(2) in a
loop for up to GETPORT_MAXTRY - 1 times, attempting to use the same port#
for all four cases. If these attempts fail, the last attempt allows
the 4 cases to use different port #s. After this function has succeeded,
the second function, called complete_service(), does the rest of what
create_service() did.
The three daemons mountd, rpc.lockd and rpc.statd all have a
create_service() function that is patched in a similar way. However,
create_service() has non-trivial differences for the three daemons
that made it impractical to share the same functions between them.

Secondly, a few improvements to the driver from Andrew Boyer,
support hint to allow devices to not attach, add VLAN_HWTSO
capability so vlans can use TSO, fix in the interrupt handler
to make sure the stack TX queue is processed. Oh, and also
make sure IPv6 does not cause a re-init in the ioctl routine.
Thanks for your efforts Andrew!
Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine

this.
VM_PAGER_AGAIN to VM_PAGER_ERROR for the uwritten pages. Return
VM_PAGER_AGAIN for the partially written page. Always forward at least
one page in the loop of vm_object_page_clean().
VM_PAGER_ERROR causes the page reactivation and does not clear the
page dirty state, so the write is not lost.
The change fixes an infinite loop in vm_object_page_clean() when the
filesystem returns permanent errors for some page writes.

This is in no way a complete DFS/radar detection implementation!
It merely creates an abstracted interface which allows for future
development of the DFS radar detection code.
Note: Net80211 already handles the bulk of the DFS machinery,
all we need to do here is figure out that a radar event has occured
and inform it as such. It then drives the DFS state engine for us.
The "null" DFS radar detection module is included by default;
it doesn't require a device line.
This commit:
* Adds a simple abstracted layer for radar detection state -
sys/dev/ath/ath_dfs/;
* Implements a null DFS module which doesn't do anything;
(ie, implements the exact behaviour at the moment);
* Adds hooks to the ath driver to process received radar events
and gives the DFS module a chance to determine whether
a radar has been detected.
Obtained from: Atheros
Please note - this doesn't in any way constitute a full DFS
implementation, it merely adds the relevant capability bits and
radar detection threshold register access.
The particulars:
* Add new capability bits outlining what the DFS capabilities
are of the various chipsets.
* Add HAL methods to set and get the radar related register values.
* Add AR5212 and AR5416+ DFS radar related register value
routines.
* Add a missing HAL phy error code that's related to radar event
processing.
* Add HAL_PHYERR_PARAM, a data type that encapsulates the radar
register values.
The AR5212 routines are just for completeness. The AR5416 routines
are a super-set of those; I may later on do a drive-by pass to
tidy up duplicate code.

default dispatch method to NETISR_DISPATCH_DIRECT in order to force
direct dispatch. This adds a fairly negligble overhead without
changing default behavior, but in the future will allow deferred or
hybrid dispatch to other worker threads before link layer processing
has taken place.
For example, this could allow redistribution using RSS hashes
without ethernet header cache line hits, if the NIC was unable to
adequately implement load balancing to too small a number of input
queues -- perhaps due to hard queueset counts of 1, 3, or 8, but in
a modern system with 16-128 threads. This can happen on highly
threaded systems, where you want want an ithread per core,
redistributing work to other queues, but also on virtualised systems
where hardware hashing is (or is not) available, but only a single
queue has been directed to one VCPU on a VM.
Note: this adds a previously non-present assertion about the
equivalence of the ifnet from which the packet is received, and the
ifnet stamped in the mbuf header. I believe this assertion to
generally be true, but we'll find out soon -- if it's not, we might
have to add additional overhead in some cases to add an m_tag with
the originating ifnet pointer stored in it.

When this rule triggers it creates a dynamic rule, but this
dynamic rule should forward packets only in forward direction.

triggers when some dynamic rule is already executed.

The binutils update in r218822 caused the MIPS n64 dynamic binaries to
fail because the ".interp" section is not in the initial sections.
This happens because elf64bmip-defs.sh overrides INITIAL_READONLY_SECTIONS
to add ".MIPS.options" sections instead of the ".reginfo" section used
by n32.
This used to work fine, but after r218822, INITIAL_READONLY_SECTIONS also
contains the .interp section, so the override has to be done differently.

In msgbuf_reinit() and msgbuf_init(), we weren't initializing the mutex.
Depending on the contents of memory, the LO_INITIALIZED flag might be
set on the mutex (either due to a warm reboot, and the message buffer
remaining in place, or due to garbage in memory) and in that case, with
INVARIANTS turned on, we would trigger an assertion that the mutex had
already been initialized.
Fix this by bzeroing the message buffer mutex for the _init() and _reinit()
paths.
