It's kinda bogus that we generate a 24 (?) byte filehandle (2 x int32
fsid and 16 byte VFS fhandle) and pad it out to 64 bytes for NFSv3 with
garbage. The whole point of NFSv3's variable filehandle length was
to allow for shorter handles, both in memory and over the wire. I plan
on taking a shot at fixing this shortly.

o use vp->type rather than vaddr.type and eliminate call to
VOP_GETATTR. Bruce says that vp->type is valid at this
point.

I observed some anomalous behavior while testing a 3c905C with a
Dell PowerEdge 4300/500 dual PIII 500Mhz system. The NIC would seem
to work correctly most of the time but would sometimes fail to receive
certain packets, in particular NFS create requests. I could mount
an NFS filesystem from the PowerEdge and do an ls on it, but trying
to do a "touch foo" would hang. Monitoring traffic from another host
revealed that the client was properly sending an NFS create request
but the server was not receiving it. It *did* receive it when I
ran the same test with an Intel fxp card.
I don't understand the exact mechanics of this strange behavior, but
resetting the receiver and transmitter seems to get rid of it. I used
to perform an RX and TX reset in xl_init(), but stopped doing it there
because on 3c905B and later cards this causes the autoneg session to
restart, which would lead to the NIC waiting a long time before exchanging
traffic after being brought up the first time. Apparently the receiver
and transmitter resets should be performed at least once when initializing
the card.
Hopefully this will cure problems that people have been having with the
3c905C -- this was the only strange behavior that I have observed with
the 3c905C so far which does not appear with the 3c905B or 3c905.
eisa_add_intr() which now takes an additional arguement (one of
EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE).
The flag RR_SHAREABLE has no effect when passed to
bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as
the eisa_alloc_resource() call (bus_alloc_resource method) now deals
with this flag directly, depending on the device ivars.
This change does nothing more than move all the 'shared = inb(foo + iobsse)'
nonesense to the device probe methods rather than the device attach.
Also, print out 'edge' or 'level' in the IRQ announcement message.

o Add field to dev_desc for the size of the io port range. This isn't

If you build this into your kernel, you will need to rebuild pccardd.
_or_ you may specify "log logamount number" to set logging specifically
the rule.
In addition, "ipfw resetlog" has been added, which will reset the
logging counters on any/all rule(s). ipfw resetlog does not affect
the packet/byte counters (as ipfw reset does), and is the only "set"
command that can be run at securelevel >= 3.
This should address complaints about not being able to set logging
amounts, not being able to restart logging at a high securelevel,
and not being able to just reset logging without resetting all of the
counters in a rule.
Specifically intended for removing -fschg ("INSTALLFLAGS_EDIT=:S/schg/uchg/")
this makes the NOFSCHG flag redundant. NOFSCHG will still be honoured by
bsd.lib.mk but is valid for buildworld only. NOFSCHG is still implemented in
the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }"
to emphasize the fact that NOFSCHG is only supported in a limited
fashion and for buildworld.
The interface and implementation are such that future use of flags such
as sappnd can also be easily removed or altered (perhaps to uappnd).

I did some tcpdumping the other day and noticed that GETATTR calls
were frequently followed by an ACCESS call to the same file. The
attached patch changes nfs_getattr to fill the access cache as a side
effect. This is accomplished by calling ACCESS rather than
GETATTR. This implies a modest overhead of 4 bytes in the request and
8 bytes in the response compared to doing a vanilla GETATTR.
...
[The patch comprises two parts] The first
is the "real" patch, the second counts misses and hits rather than
fills and hits. The difference is subtle but important because both
nfs_getattr and nfs_access now fill the cache. It also changes the
default value of nfsaccess_cache_timeout to better match the attribute
cache. IMHO, file timestamps change much more frequently than
protection bits.
