Currently, many drivers support more than one bus of ISA, EISA, MCA,
PCI.
Before this commit, we had, for example, some SCSI devices listed more
than once, iirc, some up to three times (ISA/EISA, MCA, PCI).
Since now the "device" line is common for all of them and they only
differ for the hints stuff, I did the following:
First, list Busses: (E)ISA, MCA, PCI and explain, that only ISA
needs the hints stuff.
Move NIC/SCSI stuff, which were the only split sections, behind these
stuff. Describe all drivers only one time and list all supported
chips.
List all device (+ hints for ISA, if possible).
I've also added few additional supported chips to some drivers, xl for
example and some SCSI drivers.
Also, softupdates is no longer disabled by default, so the comment should
not say, it's not enabled by default due to license issues.

controller chip. This chip is currently being used on the NetGear
FA312-TX adapter, which I guess is a replacement for the FA310-TX
(PNIC-based).
I added support for this chip by modifying the sis driver since
the SiS 900 and the NS DP83815 have almost the same programming
interface (the RX filter programming and PHY access methods are
different, but the general configuration, DMA scheme and register
layout are identical).
I would have had this done a lot sooner, but getting the damn MAC
address out of the EEPROM proved to be more complicated than expected.
SYSCTL_LONG macro to be consistent with other integer sysctl variables
and require an initial value instead of assuming 0. Update several
sysctl variables to use the unsigned types.

sure that it really is by issuing a ISPCTL_ABORT_CMD just on the
off chance the f/w will start it up again and, ha ha, start using
the DMA resources we gave it but are now taking away.
insertion of a CF card, for random values of N > 1. With these fixes,
I've been able to do 100 insert/remove of the cards w/o a crash with
lots of system activity going on that in the past would help trigger
the crash.
The problem:
FreeBSD creates dev_t's on the fly as they are needed and never
destroys them. These dev_t's point to a struct disk that is used for
housekeeping on the disk. When a device goes away, the struct disk
pointer becomes a dangling pointer. Sometimes when the device comes
back, the pointer will point to the new struct disk (in which case the
insertion will work). Other times it won't (especially if any length
of time has passed, since it is dependent on memory returned from
malloc).
The Fix:
There is one of these dev_t's that is always correct. The
device for the WHOLE_DISK_SLICE is always right. It gets set at
create_disk() time. So, the fix is to spend a little CPU time and
lookup the WHOLE_DISK_SLICE dev_t and use the si_disk from that in
preference to the one that's in the device asking to do the I/O. In
addition, we change the test of si_disk == NULL meaning that the dev
needed to inherit properties from the pdev to dev->si_disk !=
pdev->si_disk. This test is a little stronger than the previous test,
but can sometimes be fooled into not inheriting. However, the results
of this fooling are that the old values will be used, which will
generally always be the same as before. si_drv[12] are the only
values that are copied that might pose a problem. They tend to change
as the si_disk field would change, so it is a hole, but it is a small
hole.
One could correctly argue that one should replace much of this code
with something much much better. I would be on the pro side of that
argument.
