As usual, I can't see your code from here so can't tell why it's segmentation faulting. if I had to guess, I'd guess you were feeding integers into crc_add instead of pointers to integers.

Code:

// For integers, objects, etc 
crc_add(&crc, &object, sizeof(object));
// for arrays
crc_add(&crc, array, sizeof(array));
// for a pointer
crc_add(&crc, pointer, sizeof(*pointer));
// for a string
crc_add(&crc, string, strlen(string));

This is all from basic understanding of pointers in the C language.

tr

TR(4)							   BSD Kernel Interfaces Manual 						     TR(4)

NAME

     tr -- TROPIC based shared memory Token-Ring cards device driver

SYNOPSIS

     tr0 at isa? port 0xa20 iomem 0xd800 irq ?
     tr* at isa? port ? irq ?
     tr* at isapnp?
     tr* at mca? slot ?
     tr* at pcmcia? function ?

DESCRIPTION

     The tr device driver supports TROPIC I based shared-memory Token-Ring cards.

HARDWARE

     Supported cards include the following IBM and 3Com models:

	   IBM	 Token-Ring Network PC Adapter

	   IBM	 Token-Ring Network PC Adapter II

	   IBM	 Token-Ring Network Adapter/A

	   IBM	 Token-Ring Network 16/4 Adapter

	   IBM	 Token-Ring Network 16/4 Adapter/A

	   IBM	 Token-Ring 16/4 Credit Card Adapter

	   IBM	 Token Ring Auto 16/4 Credit Card Adapter

	   IBM	 Turbo 16/4 Token Ring PC Card

	   IBM	 16/4 ISA Adapter

	   IBM	 Auto 16/4 Token-Ring ISA Adapter

	   IBM	 Token Ring 16/4 Credit Card Adapter

	   IBM	 Token Ring Auto 16/4 Credit Card Adapter

	   IBM	 Turbo 16/4 Token Ring PC Card

	   3Com  3C619 TokenLink

	   3Com  3C319 TokenLink Velocity

	   3Com  3C389 TokenLink Velocity PC Card

SOURCE ROUTING

     Setting IFF_LINK0 enables Token-Ring source routing.  Setting IFF_LINK1 uses all-routes broadcasts otherwise single-route broadcasts are
     used.

NOTES

     The MCA attachment has been only tested on IBM Token Ring 16/4 Adapter/A so far.  It doesn't support ifmedia(4) yet, too.

SEE ALSO

     ifmedia(4), intro(4), isa(4), isapnp(4), mca(4), pcmcia(4), ifconfig(8)

HISTORY

     The tr driver appeared in NetBSD 1.4.

BUGS

     The PCMCIA attachment does not work with the cbb(4) CardBus driver.
