This partially reverts df55485085 but still fixes the leak. It was
overlooked (sigh) that some packets will exceed MHLEN and cannot be
physically contiguous without clustering, but we don't actually need
it to be. m_defrag() should pull up enough for any of the headers that
we do need to be accessible.

When we enter C2+ state via memory read, it may take chipset some
time to stop CPU. Extra register read covers that time. But MWAIT
makes CPU stop immediately, so we don't need to waste time after
wakeup with interrupts still disabled, increasing latency.
On my system it reduces ping localhost latency, waking up all CPUs
once a second, from 277us to 242us.

Even though the information is very limited, it seems the intent of
this flag is to control ACPI_BITREG_BUS_MASTER_STATUS use for C3,
not force ACPI_BITREG_ARB_DISABLE manipulations for C2, where it was
never needed, and which register not really doing anything for years.
It wasted lots of CPU time on congested global ACPI hardware lock
when many CPU cores were trying to enter/exit deep C-states same time.
On idle 80-core system it pushed ping localhost latency up to 20ms,
since badport_bandlim() via counter_ratecheck() wakes up all CPUs
same time once a second just to synchronously reset the counters.
Now enabling C-states increases the latency from 0.1 to just 0.25ms.

This structure is shared among multiple instances of a driver, so we
should ensure that it doesn't somehow get treated as if there's a
separate instance per interface. This is especially important for
software-only drivers like wg.
DEVICE_REGISTER() still returns a void * and so the per-driver sctx
structures are not yet defined with the const qualifier.

There are no major functional changes; this mostly contains

It closes tiny race when the flag could be set between being cleared

I think it allowed to avoid some TX thread wakeups while the socket
buffer is full. But add there another options if ic_check_send_space
is set, which means socket just reported that new space appeared, so
it may have sense to pull more data from ic_to_send for better TX
coalescing.

specific type of errors. Report RX errors to OS as sum
of all those counters: CRC errors, illegal bytes, checksum,
length, undersize, fragment, oversize and jabber errors.
There is no HW counter for frames with invalid L3/L4 checksums

Also add a "rx_errors" sysctl with a copy of netstat IERRORS
