interrupts that were scheduled. Testing shows it didn't really do very much
and it makes the code a little more complicated (which is never a good thing).
Also fix the rambuffer offset initialization for the 512K/64K SRAM case
(512K total using 64K chips). It should be 0. The only case with a
non-standard rambuffer offset address is 1024K/64K according to the
SysKonnect manual. (My card has the 1024/64 configuration and I don't know
which card uses the 512/64 configuration, if any, so I'm not sure that
this was really a problem for anyone.)

Cross Platform Changes
The driver has been reorgainsed based ideas from Brad Parker's port to Linux
to seperate OS Dependant and Independant sections.
I have backends for FreeBSD 2.2.x/3.x and 4.x newbus, BSDI, OpenBSD and NetBSD.
This commit has FreeBSD 2.2.8/2.2-stable/3.x and FreeBSD 4.x newbus backends.

Some code obtained from: Linux bttv driver
gigabit ethernet adapters. This includes two single port cards
(single mode and multimode fiber) and two dual port cards (also single
mode and multimode fiber). SysKonnect is currently the only
vendor with a dual port gigabit ethernet NIC.
The ports on dual port adapters are treated as separate network
interfaces. Thus, if you have an SK-9844 dual port SX card, you
should have both sk0 and sk1 interfaces attached. Dual port cards
are implemented using two XMAC II chips connected to a single
SysKonnect GEnesis controller. Hence, dual port cards are really
one PCI device, as opposed to two separate PCI devices connected
through a PCI to PCI bridge. Note that SysKonnect's drivers use
the two ports for failover purposes rather that as two separate
interfaces, plus they don't support jumbo frames. This applies to
their Linux driver too. :)
Support is provided for hardware multicast filtering, BPF and
jumbo frames. The SysKonnect cards support TCP checksum offload
however this feature is not currently enabled (hopefully it will
be once we get checksum offload support).
There are still a few things that need to be implemeted, like
the ability to communicate with the on-board LM80 voltage/temperature
monitor, but I wanted to get the driver under CVS control and into
-current so people could bang on it.
A big thanks for SysKonnect for making all their programming info
for these cards (and for their FDDI and token ring cards) available
without NDA (see www.syskonnect.com).
clears out the transmit queue and zeroes the downlist pointer register,
but xl_txeof() isn't called before xl_start() tries to queue more packets,
xl_start() will think that the DMA is still in progress and not update
the downlist register again, thus causing packets to sit in the transmit
queue forever.

in ti_rxeof() instead. This doesn't really seem to provide much in the
way of a performance boost, and I'm pretty sure it can cause mbuf leakage
in some extreme cases.
isp_io_map, isp_no_fwload, isp_fwload, isp_no_nvram, isp_fcduplex
which are all bitmaps of isp instances that should or shouldn't
map memory space, I/O space, not load f/w, load f/w, ignore nvram,
not ignore nvarm, set full duplex mode. Also have an isp_seed value
that we can use to generate a pseudo seed for a synthetic WWN.
Other minor cosmetic cleanup. Add in support for the Qlogic ISP
2200. Very important change where we actually check now to see
whether we were successful in mapping request and response queues
(and fibre channel scratch space).
compiles cleanly on the Alpha. (On the alpha, the port type is an int,
not a short).
Cast a couple of pointers to ints via 'uintptr_t' rather than 'unsigned
int' since uintptr_t is long (64 bit) on Alpha, as are pointers.
few changes:
- there was a bug in rl_list_tx_init(): it was calculating the registers
to initialize incorrectly. Not a problem on the x86 where unaligned
access are allowed, but a problem on the alpha.
- set rl_btag accordingly depending on the machine type
- rl_rxeof() needs to be sure to longword-align the packet data. This
is a little tricky since we copy the data out of the receive buffer
using m_devget(), however there's no way to tell m_devget() to fill
in the mbufs starting at a particular offset. To get around this,
we tell m_devget to copy bytes+2 bytes starting at offset offset-2. This
results in the proper alignment, and we can trim off the two leading
bytes afterwards with m_adj(). We also allocate some extra space before
the start of the receive buffer so that we don't get into trouble in
the case where offset == 0.
- redefine vtophys() in if_rlreg.h for the alpha.
Making this chipset work on the alpha is sort of the inverse of putting
a jet engine on a rowboat (putting a propeller on a 747?) but when
you can get these things for $5 a pop, it's hard to stop people from
buying them.
positively not let ti_encap() fill up the TX ring all the way and wrap
around. This fixes a potential transmit lockup where a really fast
machine (or particular TX traffic pattern) can overrun the end of the
ring.

like the original PNIC and the MX98715A (from which the PNIC II is derived).
This requires special handling. Save the card type, and in mx_calchash(),
if we see that the card is a PNIC, return only the low 7 bits of the
hash instead of the low 9 bits.

2) Add probing for generic USB host controllers as well so we get them all

Also removed the BSDI support (for now)
This allows the driver to be loaded/unloaded as a KLD
and loaded in the boot loader phase whithout making a custom kernel.
happens if you have a BIOS with a 'Plug & Play OS' setting and you leave
it set to 'Yes.' This is wrong for FreeBSD (and LoseNT): it should be set
to 'No.' Apparently it's still possible to map the iobase of the NIC and
have the card work by reading the config space manually (which is what
the driver does if pci_map_port() fails) but we need to warn the user to
do fix their machine anyway. Anyway, warn the user to check the 'Plug &
Play OS' setting in their BIOS if mapping the io space fails.
The driver now identifies the IBM PCI-PCI Bridge fitted to newer
Matrox cards and initialises it.

via an IBM PCI-PCI bridge (82351 or 82352 or 82353)
The driver must identify if it is on a secondary PCI bus, which is
created via the IBM PCI-PCI bridge. If it is, then it must initialise
the IBM PCI-PCI bridge correctly.
To do this, the following new functions are added.
Because they use the pcici_t tag, they are considered 2.2 compatibility APIs
pcici_t * pci_get_parent_from_tag(pcici_t tag);
int pci_get_bus_from_tag(pcici_t tag);
(The _from_tag suffix is used to prevent clashes with similarly named
newbus PCI API functions)

The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it. cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.
cdevsw_add() will print an message if the d_maj field looks bogus.
Remove nblkdev and nchrdev variables. Most places they were used
bogusly. Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.
Move bdevsw() and devsw() functions to kern/kern_conf.c
Bump __FreeBSD_version to 400006
