This way we know how to connect to secondary node when we are primary.
The same variable is used by the secondary node - it only accepts
connections from the address stored in 'remote' variable.
In cluster configurations it is common that each node has its individual
IP address and there is one addtional shared IP address which is assigned
to primary node. It seems it is possible that if the shared IP address is
from the same network as the individual IP address it might be choosen by
the kernel as a source address for connection with the secondary node.
Such connection will be rejected by secondary, as it doesn't come from
primary node individual IP.
Add 'source' variable that allows to specify source IP address we want to
bind to before connecting to the secondary node.

1. The PBVM is in region 4, so if we want to make use of it, we
need region 4 freed up.
2. Region 4 and above cannot be represented by an off_t by virtue
of that type being signed. This is problematic for truss(1),
ktrace(1) and other such programs.
POSIX does not require the shell to fork for a subshell environment, and we
use that possibility in various ways (command substitutions with a single
command and most subshells that are the final command of a shell process).
Therefore do not tie subshells to forking in the man page.
Command substitutions with expansions are a bit strange, causing a fork for
$(...$(($x))...) because $x might expand to y=2; they will probably be
changed later but this is how they work now.
Give it a good go (32 attempts) and then print out a warning that's
going to occur whether HAL debugging is enabled or not. Then don't
abort the radio setup; just continue merrily along.
This should fix the issue that users were having where scanning would
occasionally fail on the active channel, causing traffic to cease
until the radio scanned again.

not needed.
These calibrations are only applicable if the chip operating mode
engages both interleaved RX ADCs (ie, it's compensating for the
differences in DC gain and DC offset -between- the two ADCs.)
Otherwise the chip reads values of 0x0 for the secondary ADC
(as I guess it's not enabled here) and thus writes potentially
bogus info into the chip.
I've tested this on the AR9160 and AR9280; both behave themselves
in 11g mode with these calibrations disabled.
for fixing them based on the ath9k related TXQ fixes.
I've done this so people can go over the history of the diffs to the original

- A closer inspection of the OpenSolaris code indicates the block store
workaround is only necessary in case of BUS_DMASYNC_POSTREAD.
- Mark some unused parameters as such.
In some cases as udp6_connect() without an earlier bind(2) to an
address, v4-mapped scokets allowed and a non mapped destination
address, we can end up here with both v4 and v6 indicated:
inp_vflag = (INP_IPV4|INP_IPV6|INP_IPV6PROTO)
In that case however laddrp is NULL as the IPv6 path does not
pass in a copy currently.

still build it.
While it may be a perfect win in some scenarios, it still troubles users
(see PRs) in general cases. In addition we are still allocating resources
even if disabled by sysctl and still leak arp/nd6 entries in case of
interface destruction.

This commit really is "fix the OFDM duration calculation to match reality when
running in 802.11g mode."
The AR5212 init vals set AR_MISC_MODE to 0x0 and all the bits that can be set are
set through code.
The AR5416 and later initvals set AR_MISC_MODE to various other values (with
the AR5212 AR_MISC_MODE options cleared), which include AR_PCU_CCK_SIFS_MODE .
This adds 6uS to SIFS on non-CCK frames when transmitting.
This fixes the issue where _DATA_ 802.11g OFDM frames were being TX'ed with
the ACK duration set to 38uS, not 44uS as on the AR5212 (and other devices.)
The AR5212 TX pathway obeys the software-programmed duration field in the packet,
but the 11n TX pathway overrides that with a hardware-calculated duration. This
was getting it wrong because of the above AR_MISC_MODE setting. I've verified
that 11g data OFDM frames are now being TXed with the correct ACK+SIFS duration
programmed in.
Since ath9k does some slightly different bit fiddling when setting up
the TX queues, it may that the TX queue setup/reset functions will need
overriding later on.

- Always enable the HyperTransport MSI mapping window for HyperTransport
to PCI bridges (these show up as HyperTransport slave devices).
The mapping windows in PCI-PCI bridges are enabled by existing code
in the PCI-PCI bridge driver as MSI requests propagate up the device
tree, but Host-PCI bridges don't really show up in that tree.
- If the PCI device at domain 0 bus 0 slot 0 function 0 is not a
HyperTransport device, then blacklist MSI on any other HT devices in
the system. Linux has a similar quirk.
