This adds support for version 10, revision 01, but it should also work
without changes for the 0901 model, at least until we get drivers for the
two different wifi chips involved.
Many users contributed to and tested the various patchsets floating around
for the past year that have eventually evolved into this checkin, most notably
Richard Neese who provided the bulk of the kernel config file.

so that we don't need an empty implementation of it for every Marvell platform
that has no PCI. This allows the removal of the SheevaPlug-specific stub and
config files, and eliminates the need to add similar stubs for future models.
Marvell platforms that do expose PCI are compiled with 'device pci' which
causes the real (non-weak) implementation in dev/fdt/fdt_pci.c to be used.

This uses the recently-added jemalloc(3) feature of setting the lg_chunk
tuning option to zero to request that memory be allocated in the smallest
chunks possible. Without this option, the default is to initally map 8MB,
and then the mlockall() call wires that entire allocation even though the
program only uses a few Kbytes of it at runtime.

cannot be freed while do_pass_accept_req is running. This closes a race
where do_pass_establish on another CPU (the driver chose a different
queue for the new tid) expands the synq entry into a full PCB and then
releases the only hold on it, all while do_pass_accept_req is still
running.

* Add HTINFO field decoding to ieee80211_ies_expand() - it's likely not
100% correct as it's not looking at the draft 11n HTINFO location,
but I don't think anyone will care.
* When doing an IBSS join make sure the 11n channel configuration
is used - otherwise the 11a/11bg channel will be used
and there won't be any chance for an upgrade to 11n.
* When creating an IBSS network, ensure the channel is updated to an
11n channel so other 11n nodes can see it and speak to it with MCS
rates.
* Add a bit of code that's disabled for now which handles the HT
field updating. This won't work out very well with lots of adhoc
nodes as we'd end up ping-ponging between the HT configuration for
each node. Instead, we should likely only pay attention to the
"master" node we initially associated against and then ensure we
propagate that information forward in our subsequent beacons. However,
due to the nature of IBSS (ie, there's no specific "master" node in
the specification) it's unclear which node we should lift the HT
parameters from.
So for now this assumes the HT parameters are squirreled away in the
initial beacon/probe response.
So there's some trickiness here.
With ap/sta pairing, the probe response just populates a legacy node
and the association request/response is what is used for negotiation
11n-ness (and upgrading things as needed.)
With ibss networks, the pairing is done with probe request/response,
with discovery being done by creating nodes when new beacons in the
IBSS / BSSID are heard. There's no assoc request/response frames going on.
So the trick here has been to figure out where to upgrade things.
I don't like how I just taught ieee80211_sta_join() to "speak" HT -
I'd rather there be an upgrade path when an IBSS node joins and there
are HT parameters present. Once I've done that, I'll kill this
HT special casing that's going on in ieee80211_sta_join().
Tested:
* AR9280, AR5416, AR5212 - basic iperf and ping interoperability tests
whilst in a non-encrypted adhoc network.
TODO:
* Fix up the HT upgrade path for IBSS nodes rather than adding code
in ieee80211_sta_join(), then remove my code from there.
* When associating, there's a concept of a "master" node in the IBSS
which is the node you first joined the network through. It's possible
the correct thing to do is to listen to HT updates and configure WME
parameters from that node. However, once that node goes away, which
node(s) should be listened to for configuration changes?
For things like HT channel width, it's likely going to be ok to
just associate as HT40 and then use the per-neighbor rate control
and HTINFO/HTCAP fields to figure out which rates and configuration
to speak. Ie, for a 20MHz 11n node, just speak 20MHz rates to
it. It shouldn't "change", like what goes on in AP/STA configurations.
the separate ath0 TX taskq.
Whilst here, make sure that the TX software scheduler is also
running out of the TX task, rather than the ath0 taskqueue.
Make sure that the tx taskqueue is blocked/unblocked as necessary.
This allows for a little more parallelism on multi-core machines,
as well as (eventually) supporting a higher task priority for TX
tasks, allowing said TX task to preempt an already running RX or
TX completion task.
Tested:
* AR5416, AR9280 hostap and STA modes
- Make bge_lookup_{rev,vendor}() static.
- Factor out chip identification rather than duplicating the code.
- Sanitize bge_probe() a bit (don't hardcode buffer sizes, allow
bge_lookup_vendor() to return NULL so the excessive panic() three
can be removed there, etc.) and return BUS_PROBE_DEFAULT rather than
hardcoding 0.
- According to the Linux tg3 driver, BCM57791 and BCM57795 aren't
capable of Gigabit Ethernet.
- Check the return value of taskqueue_start_threads().
lle_event replaced arp_update_event after the ARP rewrite and ended up
in if_ether.h simply because arp_update_event used to be there too.
IPv6 neighbor discovery is going to grow lle_event support and this is a
good time to move it to if_llatbl.h.
The two in-tree consumers of this event - OFED and toecore - are not
affected.
