bzero(ptr, sizeof(DC_RXLEN * 5));
which should obviously be:
bzero(ptr, DC_RXLEN * 5);
Looks like this bug may have reduced the effectiveness of the
workaround for the hardware bug in the PNIC chips.

o Remove register keyword
o ANSIfy prototypes
o Remove "return;" at the end of void functions
o Remove trailing spaces
o Don't align local variables with tabs and reorder them
o Don't use /* FOO */ at the end of a #ifdef FOO block if
it's a small block
- Other non-functional changes :
o 6 -> ETHER_ADDR_LEN
o Don't initialize if_output; ether_ifattach() does it for us
hinge on the "verb" parameter which the class gets to interpret as
it sees fit.
Move the entire request into the kernel and move changed parameters
back when done.
Sleep on the vnode interlock while waiting for another
caller to increment fi_readers or fi_writers. Hold the
vnode interlock while incrementing fi_readers or fi_writers
to prevent a wakeup from being missed.
Only access fi_readers and fi_writers while holding the vnode
lock. Previously fifo_close() decremented their values without
holding a lock.
Move resource deallocation from fifo_close() to fifo_inactive(),
which allows the VOP_CLOSE() call in the error return path in
fifo_open() to be removed. Fifo_open() was calling VOP_CLOSE()
with the vnode lock held, in violation the current vnode locking
API. Also the way fifo_close() used vrefcnt() to decide whether
to deallocate resources was bogus according to comments in the
vrefcnt() implementation.

the lameness of the kstack code. The EPC overhaul de-lame-ified the
kstack code by removing the need for contigmalloc(). We can now
allocate stacks using malloc(). We probably want to make the stacks
swappable as well so that we can make it MI. But that's another story.
-Werror build with such option, but not other combinations. LINT
misses this because syscons knobs in LINT turn off a lot of code.

if we permit them to occur, the kernel panics due to our performing
EA operations using VOP_STRATEGY on the vnode. This went unnoticed
previously because there are very for users of device nodes on UFS2
due to the introduction of devfs. However, this can come up with
the Linux compat directories and its hard-coded dev nodes (which will
need to go away as we move away from hard-coded device numbers).
This can come up if you use EA-intensive features such as ACLs and
MAC.
The proper fix is pretty complicated, but this band-aid would be
an excellent MFC candidate for the release.
