with some cards that causes them to become deselected after probing for
switch capabilities. The old workaround fixes the behavior with some cards,
but causes problems with the cards the behave correctly and don't become
deselected. Forcing a deselect then reselect appears to work correctly
with all cards in initial testing.
save it for later. This enables direct manipulation of the indirection
tables (although the stock driver doesn't do that right now).

1) Use the TX FIFO empty interrupts to poll the transmit FIFO usage,
instead of using own software counters and waiting for SOF
interrupts. Assume that enough FIFO space is available to execute one
USB OUT transfer of any kind when the TX FIFO is empty.
2) Use the host channel halted event to asynchronously wait for host
channels to be disabled instead of waiting for SOF interrupts. This
results in less turnaround time for re-using host channels and at the
same time increases the performance.
The network transmit performance measured by "iperf" for the "RPi-B v1
2011/12" board, increased from 45MBit/s to 65Mbit/s after applying the
changes above.
No regressions seen using:

an if_ixv instance can now set at creation time, and the receive ring
tail pointer is correctly initialized (previously, things still worked
because the receive ring tail pointer was being fixed up as a side
effect of other activity).

The random_get() system call works similar to getentropy()/getrandom()
on OpenBSD/Linux. It fills a buffer with random data.
This change introduces a new function, read_random_uio(), that is used
to implement read() on the random devices. We can call into this
function from within the CloudABI compatibility layer.

not. When doing multiqueue, we are all setup to have full 32bit RSS hash from
the card. We do not need to hide that under "ifdef RSS" and should expose that
by default so others like lagg(4) can use that and avoid hashing the traffic by
themselves.
While here, delete the FreeBSD version check and use of deprecated M_FLOWID.

IDs in initiator mode -- index in port database instead of handlers.
This makes initiator IDs persist across role changes and firmware resets,
when handlers previously assigned by firmware are lost and reused.

Aside from cleaner and more consistent code, this allows ports to be both
target and initiator same time, and easily switch from any role to any.

This means needing to be careful about buffers and keeping track

- Tweek man page.
- Remove all mention of RANDOM_FORTUNA. If the system owner wants YARROW or DUMMY, they ask for it, otherwise they get FORTUNA.
- Tidy up headers a bit.
- Tidy up declarations a bit.
- Make static in a couple of places where needed.
- Move Yarrow/Fortuna SYSINIT/SYSUNINIT to randomdev.c, moving us towards a single file where the algorithm context is used.
- Get rid of random_*_process_buffer() functions. They were only used in one place each, and are better subsumed into those places.
- Remove *_post_read() functions as they are stubs everywhere.
- Assert against buffer size illegalities.
- Clean up some silly code in the randomdev_read() routine.
- Make the harvesting more consistent.
- Make some requested argument name changes.
- Tidy up and clarify a few comments.
- Make some requested comment changes.
- Make some requested macro changes.

This commit contains large contributions from Giuseppe Lettieri and
Stefano Garzarella, is partly supported by grants from Verisign and Cisco,
and brings in the following:
- fix zerocopy monitor ports and introduce copying monitor ports
(the latter are lower performance but give access to all traffic
in parallel with the application)
- exclusive open mode, useful to implement solutions that recover
from crashes of the main netmap client (suggested by Patrick Kelsey)
- revised memory allocator in preparation for the 'passthrough mode'
(ptnetmap) recently presented at bsdcan. ptnetmap is described in

- fix rx CRC handing on ixl
- add module dependencies for netmap when building drivers as modules
- minor simplifications to device-specific routines (*txsync, *rxsync)
- general code cleanup (remove unused variables, introduce macros
to access rings and remove duplicate code,
Applications do not need to be recompiled, unless of course
they want to use the new features (monitors and exclusive open).
Those willing to try this code on stable/10 can just update the
sys/dev/netmap/*, sys/net/netmap* with the version in HEAD
and apply the small patches to individual device drivers.

The 6205 (Taylor Peak) in the Lenovo X230 works fine in 5GHz 11a and 11n HT20,
but not 11n HT40. The NIC goes RX deaf the moment HT40 is configured.
It's so RX deaf that it doesn't even hear beacons and the firmware sends
"BEACON MISS" events. That's pretty deaf.
I tried configuring up the HT40 flags in monitor mode and it worked - so
I assumed that doing the transition from 20 -> 40MHz channel configuration
when going auth->assoc (ie, after the NIC has been partially configured)
is a problem.
So for now, let's just always set them if they're available.
Tested:
* Intel 5300, STA mode, 5GHz HT/40 AP; 2GHz HT/20 AP
* Intel 6205, STA mode, 5GHz HT/40, HT20, 11a AP; 2GHz HT/20 AP
This was pointed out to me by coworkers trying to use FreeBSD-HEAD
in the office on their Thinkpad T420p laptops.
TODO:
* I don't like how the HT40 flags are configured - the whole interop/
protection config should be re-checked. Notably, I think curhtprotmode
is 0 in a lot of cases, which means "no interoperability" and i think
that's busted.
