New Feature: add pseudo device for IEEE 1394 isochronous stream and
isochronous reception routine for IEEE 1394 OHCI (fwohci). The
transmission part is under construction.

The minimum configuration options for this feature are:

# IEEE 1394 (i.LINK)
fwohci* at pci? dev ? function ?
pseudo-device fwiso 1

OCHI -> OHCI

branches: 1.10.2;
fix typo: CLear -> Clear

Add mask for getting the ACK bits out of the status area of a DMA context descriptor

- Wrap long line.
- Consistently use #define<TAB> instead of #define<SPACE>.

use OHCI_BITVAL(val, name), instead of
((val) & (name##_MASK)) >> name##_BITPOS

branches: 1.6.2;
Do not require GUID ROM, which is optional according to the OHCI spec.
Use Global UID register as is, it should be initialized by firmware.
If it is not initialized (i.e. 0), try to read GUID ROM if exists.
On my VAIO PCG-N505AS, the version register says it implement GUID ROM,
but reading GUID ROM returns all zero bytes. I'm not sure where the bug is.

Add RCS Id.

Use DMA from mbuf instead of copy in transmit.
Still use memcpy in receiving because we must use buffer fill mode
and many packets may share single receive buffer.

XXX: Workaround(?) for CXD3222: it fails to DMA for selfid packet according
to code placement. I'm not sure about the reason (cache? timing? bug?).

Fixed the bug: transmitter sometimes stop and OACTIVE bit of if_fw
never be cleared.
Fixed the bug: freeing free buffer.

Enable ieee1394_drain and ieee1394_watchdog for loss of fragment.

branches: 1.3.2;
Merge in my some of my stuff.

First Prototype implementation of network interface part for IEEE1394 (if_fw).

Current status:
Only OHCI chip is supported (fwohci).
ping (IPv4) works with Sony's implementation (SmartConnect) on Win98.
sometimes works but not stable.
Not implemented yet:
IRM (Isochronous Resource Manager) functionality.
Link layer fragmentation.
Topology map.
More to do:
clean ups
MCAP
charactor device part
dhcp

There is no entry in GENERIC config file yet.
Follow sys/dev/ieee1394/IMPLEMENTATION to enable if_fw.

branches: 1.1.4;
Beginning of a IEEE 1394 framework. An attachment for PCI OHCI controllers
and bus-independent module that just begins to print things out. No real
code behind it. THIS IS A WORK IN PROGRESS. The *reg.h are woefully
incomplete.
