Throw away the result of the peer SPAD read. The peer will write our
local SPAD and we need to keep the locally read SPAD value to check if
the remote side is up.

Reset the link stats when the link goes down. In particular, the TX and
RX index and count must be reset, or else the TX side will be sending
packets to the RX side where the RX side is not expecting them. Reset
all the stats, to be consistent.

We skip actually bringing up Rootport/Transparent configurations, so
most of this doesn't apply. Original Linux commit log:
Link training should be enabled in the driver probe for root port mode.
We should not have to wait for transport to be loaded for this to
happen. Otherwise the ntb device will not show up on the transparent
bridge side of the link.

The bits in the aux control register vary based on the processor type. In
the past we've always just set the 'smp' and "broadcast tlb/cache ops' bits,
which worked fine for the first few SoCs we supported. Now that we support
most of the cortex-a series processors, it's important to get the right bits
set based on the processor type.

The failure path for allocating rx grant refs should not try to free tx
grant refs because tx grant refs were allocated after that. Also fix the
error path for xen_net_read_mac.

Multiqueue feature will make the number of queues dynamic, so XN_LOCK_INIT
won't be that useful. Remove the macro and call mtx_init directly.
XN_LOCK_DESTROY is just dead code.

Currently neither Linux nor FreeBSD netback supports page flipping. NetBSD
still supports that. It is not sure how many people actually use page
flipping, but page flipping is supposed to be slower than copying nowadays.
It will also shatter frontend / backend address space.
Overall this feature is more of a burden than a benefit.

* Use the correct malloc type for node allocation - M_80211_NODE - so
the default node free method in net80211 will work correctly.
* Fix otus_node_alloc() to suit FreeBSD's net80211.
* .. and actually call otus_node_alloc() so there's space for the
per-node tx statistics. Otherwise, well, it will be scribbling over
random memory.
Tested:
* AR9170, STA mode
The monitor mode stuff is from the openbsd driver, but it doesn't
100% work. It doesn't seem to get all frames for all BSSes.
However, it's enough to at start debugging things. That 0xffffffff
write is /I think/ the RX filter, but I am still not 100% sure about
it all.
Then, whilst here, use the lowest rate for EAPOL frames. This is just
generally a good thing to do.
This commit adds support for MDIO present in the ThunderX SoC.
From the FDT point of view it is compatible with "octeon-3860-mdio"
however only C22 mode is used.
The code also implements lmac_if interface functions.

- The driver consists of three main componens: PF, VF, BGX
- Requires appropriate entries in DTS and MDIO driver
- Supports only FDT configuration
- Multiple Tx queues and single Rx queue supported
- No RSS, HW checksum and TSO support
- No more than 8 queues per-IF (only one Queue Set per IF)
- HW statistics enabled
- Works in all available MAC modes (1,10,20,40G)
- Style converted to BSD according to style(9)
- The code brings lmac_if interface used by the BGX driver to
update its logical MACs state.
