ata_detach() to implement IOCATAATTACH/IOCATADETACH ioctls.
This will permit channel drivers to properly shutdown port hardware on channel
detach and init it on attach.
o mark phy type to indicate 1/2 or 1/4-rate operation
o use phy type instead of channel attributes to identify 1/2 and 1/4-rate

o general cleanup of code including move phy constants to ah_internal.h
Eventually this code should go away and we should use the net0211 equivalents.

As opposite to ch_attach() add new ch_detach() method to deallocate/disable

- Update to firmware 1.4.39 for dual-chip NIC (10G-PCIE2-xxx)
support, and SFP+ i2c support
- Identify newer "B" NICs (10G-PCIEx-8B-x) correctly, rather than
mis-identifying them as "A" NICs (cosmetic only)
- Identify the IFM_10G_LRM ifmedia type, where applicable.

Prior to this fix, IEVENT register was always cleared before calling
tsec_error_intr_locked(), which prevented error recovery actions from
happening with polling enabled (and could lead to serious problems, including
controller hang).

If speed of link between two devices is slower than the reported max
speed of both endpoints, the current driver will fail and be unable to
negotiate.
Summary:
Test negotiated speed by reading the CSRROM into a dummy variable.
If that read fails, decrement our speed and retry. If all else fails,
go to lowest speed possible(0).
Report speed to the user.
Add display of the Bus Info Block when debug.firewire_debug > 1
Support the Bus Info Block(1394a-2000) method of speed detection.
I also should note that I am moving "hold_count" to 0 for future
releases.
This variable determines how many bus resets to "hold" a removed
firewire device before deletion. I don't feel this is useful and will
probably drop support for this sysctl in the future.

first time through, then we know that we're done. If the device has
other devices that are deferred, then it must do a similar dance.
This catches both PC Cards and CardBus cards.

It allows to save some resources, not bother user with unexisting hardware

- specification claims that 1 second is just a maximum controller reset time;
implement controller reset properly to save almost 1 second of boot, and
about half second of resume time;
- enable channel interrupts only after channel status reset to fix duplicate
device creation on resume due to unwanted device connection event;
- as described in specification, wait for disk ready status after channel
power-up; it is not so important when disk already touched by BIOS, but
solves device not ready problems on resume and probably some other cases.
- uncomment channel stop/start on soft-reset as it is declared mandatory by
specification; it was commented due to some random drive detection problems
on VIA and JMicron controllers, but I hope it is fixed by previous point.
Move channel softc initialization from ata_XXX_probe() to ata_XXX_attach().
Instead of calculating ata channel number as position in child device list,
pass it's real number directly from controller probe routine using ivars.
It is simpler and IMHO more correct.
Giving a charactere device execute permissions doesn't have any use.
Right now there isn't a single device node in /dev that has it, except
the USB2 device node, so remove it.

longer do we require SCTP to be in the kernel for the
lib to be able to handle SCTP. We do this by moving
the CRC32c checksum into libkern/crc32.c and then adjusting
all routines to use the common methods. Note that this
will improve the performance of iSCSI since they were
using the old single 256 bit table lookup versus the
slicing 8 algorithm (which gives a 4x speed up in
CRC32c calculation :-D)
