This commit hides a kernel panic in atrtc_settime() as the clock_ts_to_ct()
does not properly convert negative tv_sec.
ps. in my opinion clock_ts_to_ct() should be rewritten to properly handle
negative tv_sec values.

This space does not require DMA syncing. It reduces lock scope of the DMA
scratch space. It allows whole DMA scratch space to be used to I/O, so now
we can fetch up to ~1000 ports from SNS.
Due to the last fact, increase maximal number of ports from 256 to 1024.
The licence grant says something exactly the same as the atheros patent
grant, which is "As long as you use this firmware on our chips, everything
is totally okay." Now, I'm pretty sure if that we /have/ to have this,
we're going to have to have it for every other firmware for every other
device in the tree.
So, I'll flip this off in -HEAD for now so people stop asking about
why rsu/urtwn don't work out of the box, and I'll kick off a larger
discussion about this in the new year.
IEEE 802.3 Clause 45 added backwards-compatible support for 2^16 PHY registers
through the addition of an additional device address frame.
Clause 45 addressing is used in 10Gbe PHYs, 802.3az EEE registers, etc. It may
make sense to provide a similar extension to the miibus interface, but I've
refrained from unilaterally doing so here.

On the host side this driver interfaces with the storage stack via the
ICL (iSCSI Common Layer) in the kernel. On the wire the traffic is
standard iSCSI (SCSI over TCP as per RFC 3720/7143 etc.) that
interoperates with all other standards compliant implementations. The
driver is layered on top of the TOE driver (t4_tom) and promotes
connections being handled by t4_tom to iSCSI ULP (Upper Layer Protocol)
mode. Hardware assistance in this mode includes:
- Full TCP processing.
- iSCSI PDU identification and recovery within the TCP stream.
- Header and/or data digest insertion (tx) and verification (rx).
- Zero copy (both tx and rx).
Man page will follow in a separate commit in a couple of weeks.

Before this change virtual ports control IOCBs were executed synchronously
via Execute IOCB mailbox command. It required exclusive use of scratch
space of driver and mailbox registers of the hardware. Because of that
shared resources use this code could not really sleep, having to spin for
completion, blocking any other operation.
This change introduces new asynchronous design, sending the IOCBs directly
on request queue and gracefully waiting for their return on response queue.
Returned IOCBs are identified with unified handle space from r292725.
The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.

I am not sure why this was split long ago, but I see no reason for it.
At this point this unification just slightly reduces memory usage, but
as next step I plan to reuse shared handle space for other IOCB types.
These are all works in progress. Notably - no wifi support just yet!
