- Fix dumping on Thunderbolt cards. Polled IO commands do not seem to
be normally acknowledged by changing cmd_status to MFI_STAT_OK.
In order to get acknowledgement of the IO is complete, the Thunderbolt

to indicate this command is being polled and to complete the
Thunderbolt wrapper and indicate the result. This flag needs to be
set in the JBOD case in case if that us using Thunderbolt card.

the non-aggregate path.
I "cheated" by using some TX setup code in our HAL that isn't present
in the atheros HAL (or Linux ath9k.)
The old path for forming aggregates was:
* setup the rate control in the first descriptor;
* call chaintxdesc() on all the frames;
* call setupfirsttxdesc() on the first descrpitor in the first
frame;
* call setuplasttxdesc() on the last descriptor in the last frame.
The new path for forming aggregates looks like the non-aggregate path:
* call setuptxdesc() on the first descriptor in the first frame;
* setup the rate control in the first descriptor;
* call filltxdesc() on each descriptor in the frame;
* if it's an aggregate - call set11n_aggr_{first, middle, last} as
appropriate (see the code for a description of what is "appropriate".)
Now, this is done primarily for the AR9300 HAL - it doesn't implement
the first set of aggregate functions. It just has the older methods
and the "first/middle/last" aggregate methods. So, let's convert the
code to use these.
Note: the AR5416 HAL in FreeBSD had that code (from me, a while ago)
and a previous commit brought it up to behave the same as the AR9300
HAL routines.
There's some further tidyups to be done - specifically, avoid doing
multiple calls to the 11n descriptor functions. I shouldn't call
clr11n_aggr(), then set11n_aggr_middle(), then also set11n_aggr_first().
On (at least MIPS) the TX descriptors are in non-cachable memory and
this will cause multiple slow writes.
I'll debug/tidy that up in a future commit.
Tested:
* AR9280, STA
* AR9280/AR9160, AP
* AR9380, STA (using a local, closed source HAL, sorry!)

them, please let me know if not). Most of these are of the form:
static const struct bzzt_type {
[...list of members...]
} const bzzt_devs[] = {
[...list of initializers...]
};
The second const is unnecessary, as arrays cannot be modified anyway,
and if the elements are const, the whole thing is const automatically
(e.g. it is placed in .rodata).
I have verified this does not change the binary output of a full kernel
build (except for build timestamps embedded in the object files).

- Testing TSO6 has led me to discover that HW RSC is
a problematic feature, it is ONLY designed to work
with IPv4 in the first place, and if IP forwarding
is done it can't be disabled as LRO in the stack,
also initial testing we've done at Intel shows an
equal performance using TSO[46] on the TX and LRO
on RX, if you ran older code on 82599 or later hardware
you actually could have detrimental performance for
this reason. So I am disabling the feature by default
and all our adapters will now use LRO instead.
- If you have flow control off and multiple queues it
was possible when the buffer of one queue becomes
full that all RX movement is stalled, to eliminate
this problem a feature bit is now set that will allow
packets to be dropped when full rather than stall.
Note, the default is to have flow control on, and this
keeps this from happening.
- Because of the recent fixes in the stack, LRO is now
auto-disabled when problematic, so I have decided to
enable it by default in the capabilities in the driver.
- There are some 1G modules used by some customers, a couple
small tweaks to properly support those in the media code.
- A note: we have now done some testing of TSO6 and using
LRO with IPv6 and it all works great!! Seeing line rate
