There are a variety of more interesting RX statistics that we should
keep track of but we don't. This is a starting point for adding more
information.
Specifically:
* now the RX rate information and some of the packet status is
passed up;
* The 32 bit or 64 bit TSF is passed up;
* the PHY mode is passed up;
* the "I'm decap'ed AMSDU!" state is passed up;
* number of RX chains is bumped to 4.
This is all mostly a placeholder for getting the data into the RX status
before we pass it up to net80211 - unfortunately we don't yet enforce
that drivers provide it, nor do we pass the provided info back up the
stack so anyone can use the data.
We're going to need to use some of this data moving forward.
Notably, now that some hardware can do AMSDU decap for us (the intel iwm
driver can do it when we flip it on; the ath10k port I'm doing does
it for us) then we need to pass it up through the stack so the duplicate
RX sequence numbers and crypto/IV details don't cause the packet to
be dropped and/or counted against a replay counter.
It's also the beginning of being able to do more interesting node
accounting in net80211. Specifically, once drivers start populating
per-packet rate information, AMPDU information, timestamps, etc,
we can start providing histograms of rate-versus-RSSI, account
for receive time spent per node and other such interesting things.
(Note: I'm also hoping to include ranging and RTT information for
future chipset support; and it's likely going to include it in
this kind of fashion.)
Replace various void * / int argument combinations with common structures:
- ieee80211_ratectl_tx_status for *_tx_complete();
- ieee80211_ratectl_tx_stats for *_tx_update();
While here, improve amrr_tx_update() for a bit:
1. In case, if receiver is not known (typical for Ralink USB drivers),
refresh Tx rate for all nodes on the interface.
2. There was a misuse:
- otus(4) sends non-decreasing counters (as originally intended);
- but ural(4), rum(4) and run(4) are using 'read & clear' registers
to obtain statistics for some period of time (and those 'last period'
values are used as arguments for tx_update()). If arguments are not big
enough, they are just discarded after the next call.
Fix: move counting into *_tx_update()
(now otus(4) will zero out all node counters after every tx_update() call)
Tested with:
- Intel 3945BG (wpi(4)), STA mode.

* Don't do the antenna switching when setting up the rate table - we don't
take into account whether it's an active antenna or not (eg shared with BT.)
I'll look into this a bit more later.
* The default antenna is still 1, I'll look into that a bit more later.
(So no, this doesn't fix it for Larry who needs ANT_B to be active, not
ANT_A.)
* My changes to the rate control setup used the wrong method for finding
a suitable rate, which led to 1M CCK frames being queued for 11a operation.
This is .. sub-optimal. Change the rate control lookup path to use
the global table instead of the per-node table, which won't be setup
until the node rate table is setup (which happens way too late in this
game.)
Tested:
* Intel 7260, 2G and 5G operation.
This changes the transmit rate control code to do a few things:
* use fixed rates (mcast, ucast, mgmt) where required.
* Don't use a hard-coded 11a or 11bg rate for non-data frames -
use what net80211 says we should use.
* use mgmtrate for EAPOL frames.
