Yes, I know that IFADDR ioctl is supposed to be deprecated... Note
that the patch was modified by me to fit better into the driver. -DG

While porting CAP to 386bsd/pk0.2.4 and now to FreeBSD Release 1.0
I found a couple of bugs associated with the packet filter. Here
are the fixes. I'm posting them here because they apply to
FreeBSD and 386bsd/pk0.2.4 and possibly to other *BSD.
The first occurs when using the packet filter to write raw
ethernet packets. The header consisting of the sender and
destination addresses and the protocol is removed and later
added back on, but with the byte order of the protocol reversed.
The fix ensures that the byte order in the protocol field is
swapped when it is removed.
The second fix ensures that SIOCGIFADDR works for BPF as claimed
in the man pages, by adding it to the ed driver. Similar fixes
will be needed for other ethernet drivers.

file override to disable fifo on 16550s:
I bought a board with two 16550's, but one of those ports has a mouse
on it. The sio driver always enables the fifo, which is a bad thing
for mice and X. The mouse is jerky and hard to use. The simple thing
is be to treat one of the ports as a non-fifo'ed UART, and I use the
flags option in my config file.
So, my config file has:
device sio0 at isa? port "IO_COM1" tty irq 4 flags 0x2 vector siointr
device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr
(patch deleted)
Cuddle { braces up where possible on if statements
Add missing splx(s) calls before some returns.
Remove extra semicolon that was keeping uha_init from returning
before the timeout occured. This should speed probing up quite
a bit!
0) FreeBSD additional include files additions
1) Rod's arpacom changes
2) Function type and return code cleanup, and all functions have correct
casting to the correct data types
3) Bugfix where driver would not function due to missing structure not
given a value.
4) General cleanup. (Theo did a lot already, I just did some more)

As reported on the -bugs list by some one, and confirmed by Julian:
> I increased AHA_RESET_TIMEOUT in aha1542.c from 1000 to 10000
> and now my 1542C is found everytime.
Changed the output of the isa probe routine, that only devices, that
have an IO address and are smaller than 0x100 to be on the motherboard.
The seagate SCSI adapter is an example of a card, that doesn't have
an IO address and works only memory mapped.
Choose older MULTIPORT version, because lastest bde version
not worked.
Don't force HUPCL for bidirectional case.
From bde:
Use bit (1 << (16 + 4)) in schedsoftcom() to avoid clash with
non-serial h/w on IRQ4.
Allow FIFO_TRIGGER in config.
Clear com->mcr_image when clearing mcr for init of 4port. The
usual value MCR_IENABLE should have broken 4ports unless
something happened to clear it later.
Turn off interrupts as well as DTR after an error waiting for
carrier (bidir dialin case).
Drain fifo more carefully.
Don't hang up if debugging.
Rearrange siointr() -> siointr1() for multiport case for speed,
lower latency and clarity.
Use suser() to check perms.
Provide missing splx() after failed perms checks.
c_ispeed == 0 means c_ispeed = c_ospeed (POSIX).
Set parameters (except speed) for c_ospeed == 0 as well as
hanging up.
Better initialization for console (fifo stuff...).
Misc. cleanups.
Fix dead hang if modem power is off.
problems in the moment are stray intr's in the ifconfig up/down.
No way to select all three interfaces on a combo card with
AUI/BNC/UTP interfaces and the performance doesn't look good.
Only tested with a ISA AUI/BNC card yet.
Added it to the list of known boards and put it into the the list for
the mailbox unlock. Maybe all board-ids over 0x42 should be in the
mailbox unlock part ?
enough tests to be considered more stable than current driver.
Lots of work by Bruce, David G., and Guido have gone into this version, and
more is to come in the future.
Support for multiple controllers is in, but doesn't work correctly with
different controllers (IDE AND MFM), but multiple alike controllers appears
to work.
Most of the stray interrupts problems should be fixed, although you will
get a couple 'extra interrupts' when disklabeling and on startup.
can actually write a sane netif device to support one of these. Note that it
was necessary to steal a netisr bit from another protocol; I took the one for
PF_DATAKIT (no great loss).
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.
NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
Entries for 800 and 820 fixed.
From vak@kiae.su:
incorporate Joerg Wunsch formatting code
correct handle timeouted operations
fixed entry for 720 media
GAP values changed suitable for possible format code addition.
Read/write GAP always 2 now.
Interleave parameter added for possible format code addition.
Many logical formats added.
720K physical drive added.
Problems: still can't read 720..820 media in 1.44 drive.
800K in HD 5.25in (maximum for DD diskettes)
1.44M in HD 5.25in (for easy distributions)
1.46M in HD 5.25in (maximum for 5.25)
Some cosmetique changes.
