Now that I understand what's going on - and the RX antenna array maps
to what the receive LNA configuration actually is - I feel comfortable
in enabling this.
If people do have issues with this, there's enough debugging now available
that we have a chance to diagnose it without writing it up as 'weird
crap.'
Tested:
* AR9285 STA w/ diversity combining enabled in EEPROM
TODO:
* (More) testing in hostap mode
and controlling this form of antenna diversity) - print out the AR9285
antenna diversity configuration at attach time.
This will help track down and diagose if/when people have connectivity
issues on cards (eg if they connect a single antenna to LNA1, yet the
card has RX configured to only occur on LNA2.)
Tested:
* AR9285 w/ antenna diversity enabled in EEPROM;
* AR9285 w/ antenna diversity disabled in EEPROM; mapping only to a
single antenna (LNA1.)
PR15662: Optimized debug info produces out of order function
parameters
When a function is inlined we lazily construct the variables
representing the function's parameters. After that, we add any
remaining unused parameters.
If the function doesn't use all the parameters, or uses them out of
order, then the DWARF would produce them in that order, producing a
parameter order that doesn't match the source.
This fix causes us to always keep the arg variables at the start of
the variable list & in the original order from the source.

This is required by POSIX, at least for pids that are not known child
processes.
Other problems with job specifications still cause wait to abort with
exit status 2.

This is only part of the PR; the behaviour for unknown/invalid pids/jobs
remains unchanged (aborts the builtin with status 2).

+ pkt-gen -f rx now remains active even when traffic stops
Previous behaviour (exit after 1 second of silence) can be
restored with the -W option
+ the -X option does a hexdump of the content of a packet (both tx and rx).
This can be useful to check what goes in and out.
+ the -I option instructs the sender to use indirect buffers
(not really useful other than to test the kernel module in the
VALE switch)
from each batch flowing on the VALE switch
- feature: add glue for 'indirect' buffers on the sender side:
if a slot has NS_INDIRECT set, the netmap buffer contains pointer(s)
to the actual userspace buffers, which are accessed with copyin().
The feature is not finalised yet, as it will likely need to deal
with some iovec variant for proper scatter/gather support.
This will save one copy for clients (e.g. qemu) that cannot
use the netmap buffer directly.
A curiosity: on amd64 copyin() appears to be 10-15% faster than pkt_copy()
or bcopy() at least for sizes of 256 and greater.
the RX antenna field.
The AR9285/AR9485 use an LNA mixer to determine how to combine the signals
from the two antennas. This is encoded in the RSSI fields (ctl/ext) for
chain 2. So, let's use that here.
This maps RX antennas 0->3 to the RX mixer configuration used to
receive a frame. There's more that can be done but this is good enough
to diagnose if the hardware is doing "odd" things like trying to
receive frames on LNA2 (ie, antenna 2 or "alt" antenna) when there's
only one antenna connected.
Tested:
* AR9285, STA mode
for the RX path.
This is different to the div comb HAL flag, that says it actually
can use this for RX diversity (the "slow" diversity path implemented
but disabled in the AR9285 HAL code.)
Tested:
* AR9285, STA operation
swap_pager_copy() is invoked, otherwise there is no reason to do so.
This will eliminate the necessity to busy pages most of the times.

Fix uninitialized memory reference in mps_read_config_page. It was
referencing a field (params->hdr.Ext.ExtPageType) that would only be
set when reading an Extended config page. The symptom was that
MPSIO_READ_CFG_PAGE ioctls would randomly fail with
MPI2_IOCSTATUS_CONFIG_INVALID_PAGE errors. The solution is to
determine whether an extended or an ordinary config page is requested
by looking at the PageType field, which should be available regardless.
Similarly, mps_user_read_extcfg_header and mps_user_read_extcfg_page,
which call mps_read_config_page, had to be fixed to always set the
PageType field. They were implicitly assuming that
mps_read_config_page always operated on Extended pages.

with merge the functions but leave out the code to save/load the VFP
registers as that requires other changes to ensure the VFP is enabled
first.
This removes storing the old fpa registers. These were never fully
supported, and the only user of this code I can find have moved to newer
CPUs which use a VFP.
this menu consistent with Console->Repeat, Console->Font, Console->Screenmap
and many others which place the default choice at the top.
NOTE: SVN r249751 changed things so that these menus highlight the active
selection, so the idea that the default choice (now at top) "can be selected
immediately by hitting ENTER" is not possible unless the default choice is
the currently active setting (e.g., on first visit to the menu). However, it
is still warranted to have the default choice at the top of the menu.

replacement comes with a great performance increase (as f_shell_escape()
uses the built-in based f_replaceall() which out-performs forking to
awk(1)). This should also improve readability slightly.
