This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is
currently not working, and ARM support has not been completed or tested on the

fields in the softc; they're ORed together in the ofw_compat_data.
I already caught myself doing 'sc->fectype == <enum val>' without masking
out the feature bits in one place, and that's sure to happen again.
Glomming them together is convenient for storing them in the ofw_compat_data
array, but there's no reason to keep them together in the softc.
When available, enabling this feature causes the hardware to write data
to the receive buffer starting at a 16-bit offset from the start address.
This eliminates the need to copy the data after receiving to re-align
the protocol headers to a 32-bit boundary.

Newer hardware splits the interrupts onto 3 different irq lines, but the
docs barely mention that there are multiple interrupts, and do not detail
how they're split up. The code now supports 1-3 irqs, and uses the same
interrupt service routine to handle all of them.
I modified the submitted changes to use bus_alloc_resources() instead of
using loops to allocate each irq separately. Thus, blame any bugs on me (I
can't actually test on imx7 hardware).

When the FEC is connected to the AXI bus (indicated by AVB flag), a
MAC reset while a bus transaction is pending can hang the bus.
Instead of resetting, turn off the ENABLE bit, which allows the
hardware to complete any in-progress transfers (appending a bad CRC
to any partial packet) and release the AXI bus. This could probably
be done unconditionally for all hardware variants, but that hasn't
been tested.

This flag is analogous to the Linux driver FEC_QUIRK_HAS_AVB. It
indicates an FEC with support for Audio Video Bridging (AVB). This
indicator is used for various other parts in the Linux driver
(drivers/net/ethernet/freescale/fec_main.c).
Use it to customize the receive/transmit buffer alignment. The receive
buffer alignment increased to 64-bytes on the i.MX 6SoloX and i.MX
7Dual. There are no hard alignment restrictions for transmit buffers on
these chips.
Fix the ffec_softc::fectype type to provide enough storage for the
feature flags.

To accomodate all variaties of Pi DTS files floating around
we look for MAC address property either in DTS node for
USB ethernet (if it exists) or at predefined path
".../usb/hub/ethernet".
After r324184 smsc_fdt_find_eth_node started to return node
with compatibility string "usb424,ec00" as an eth node.
In imported GNU dts files this node still does not have
MAC address related property, and therefor following check for
"mac-address" and "local-mac-address" fails.
To make this logic more robust do not just search for the node
but also make sure it has required property, so if node with
accepted compatibility string exists but doesn't have the
property we fall back to looking for hardoded path mentioned above.

Some BMCs support power cycling the chassis via the chassis control
command 2 subcommand 2 (ipmitool called it 'chassis power cycle'). If
the BMC supports the chassis device, register a shutdown_final handler
that sends the power cycle command if request and waits up to 10s for
it to take effect. To minimize stack strain, we preallocate a ipmi
request in the softc. At the moment, we're verbose about what we're
doing.

When using a kernel built with the GZIO config option, dumpon -z can be
used to configure gzip compression using the in-kernel copy of zlib.
This is useful on systems with large amounts of RAM, which require a
correspondingly large dump device. Recovery of compressed dumps is also
faster since fewer bytes need to be copied from the dump device.
Because we have no way of knowing the final size of a compressed dump
until it is written, the kernel will always attempt to dump when
compression is configured, regardless of the dump device size. If the
dump is aborted because we run out of space, an error is reported on
the console.
savecore(8) is modified to handle compressed dumps and save them to
vmcore.<index>.gz, as it does when given the -z option.
A new rc.conf variable, dumpon_flags, is added. Its value is added to
the boot-time dumpon(8) invocation that occurs when a dump device is
configured in rc.conf.

CAM_REQ_ABORTED sounds natural for aborting outstanding requests when
tearing down a session, but that status actually causes eligible
requests to be tried again. That's completely useless, so let's use
CAM_DEV_NOT_THERE instead. Perhaps there is a better status, but this
should be good enough. The change should affect only the session
termination.

It should be sufficient to hold the lock just for removing the session
from the session list. Everything else should be covered by the session
specific lock.
On top of that, at present we can get a deadlock caused by waiting on
the CAM SIM reference count while holding the global lock. A specific
scenario involving ZFS is this:
- concurrent termination of two sessions, S1 and S2
- session S1 completed all I/Os and sleeps in CAM waiting for device
close by ZFS;
- session S2 is also dead now, but can not forcefully complete
outstanding requests by calling iscsi_session_cleanup() from
iscsi_maintenance_thread_terminate(), since it can't get the same
global sc_lock;
- as soon as there are unfinished requests, ZFS can not do
spa_config_enter() as writer, and so can not close the device for
session S1;
- deadlock.
