These are probably generated by other PCI devices sharing the TLAN's
interrupt. The programmer's guide says to simply re-enable interrupts
and return if one of these is detected.
Prompted by bug report from: Bill Fenner
net.inet.ip.icmp.bmcastecho = 0 by removing the extra check for the
address being a multicast address. The test now relies on the link
layer flags that indicate it was received via multicast. The previous
logic was broken and replied to ICMP echo/timestamp broadcasts even
when the sysctl option disallowed them.

i contains the contents of the EP_W0_CONFIG_CTRL register.
i was being used as the array index into an array on the stack.
j is initialized to 0 as it should be.

Prior to this change, Accidental recursion protection was done by
the diverted daemon feeding back the divert port number it got
the packet on, as the port number on a sendto(). IPFW knew not to
redivert a packet to this port (again). Processing of the ruleset
started at the beginning again, skipping that divert port.
The new semantic (which is how we should have done it the first time)
is that the port number in the sendto() is the rule number AFTER which
processing should restart, and on a recvfrom(), the port number is the
rule number which caused the diversion. This is much more flexible,
and also more intuitive. If the user uses the same sockaddr received
when resending, processing resumes at the rule number following that
that caused the diversion. The user can however select to resume rule
processing at any rule. (0 is restart at the beginning)
To enable the new code use
option IPFW_DIVERT_RESTART
This should become the default as soon as people have looked at it a bit
passed to the user process for incoming packets. When the sockaddr_in
is passed back to the divert socket later, use thi sas the primary
interface lookup and only revert to the IP address when the name fails.
This solves a long standing bug with divert sockets:
When two interfaces had the same address (P2P for example) the interface
"assigned" to the reinjected packet was sometimes incorect.
Probably we should define a "sockaddr_div" to officially hold this
extended information in teh same manner as sockaddr_dl.

I'm not sure who to give the credit to, but the bug was reported by
Jennifer Dawn Myers <jdm@enteract.com>, who also supplied a patch. It
was also fixed in OpenBSD previously by andreas.gunnarsson@emw.ericsson.se,
and of course I did the homework to verify that the fix was correct per

an artificial power of two limit for malloc's sake.
in -current is over, I'll put a 2.2.x specific version in the RELENG_2_2
branch. If somebody wants a 2.2 version of this driver now, they can check
out the previous version from CVS or ask me via e-mail.
Gee people, I didn't mean to stir up such a controversy. I just wanted
to make sure I could get this thing to work with both kernel versions
and didn't want to have to maintain two separate copies. All ya hadda
do was ask. :)

This should help the behavior of mmaped files when using

This driver supports the following cards/integrated ethernet controllers:
Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100,
Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port,
Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated,
Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX.
It should also support Texas Instruments NICs that use the ThunderLAN
chip, though I don't have any to test. If you've got a card that uses
the ThunderLAN chip but isn't listed in the PCI vendor/product list in
if_tl.c, try adding it and see what happens.
The driver supports any MII compliant PHY at 10 or 100Mbps speeds in
full or half duplex. (Those I've personally tested are the National
Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro
desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation,
hardware multicast filtering, BPF and ifmedia support are included.
This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN
ethernet and FreeBSD make for a nice combination.

This apparently comes from BSDI (from Keith Bostic) via NetBSD.

2. Use need_resched instead of reset_priority. This isn't right
either, since for example you'll round-robin against equal priority FIFO
processes when lowering the priority of another process,
but this works better and a real fix needs to be in kern_synch and
not out here.
3. This is not a device driver: copyin/copyout the structure.
Althought the comments say the datasheet doesn't list the device ID
registers on the M2/MX, they seem to be there and quite alive.

is missing a heck of a lot of features, including VME, PGE, PSE, etc)
NetBSD, ported to FreeBSD by Pierre Beyssac <pb@fasterix.freenix.org> and
minorly tweaked by me.
This is a standard part of FreeBSD, but must be enabled with:
"sysctl -w net.inet.ip.fastforwarding=1" ...and of course forwarding must
also be enabled. This should probably be modified to use the zone
allocator for speed and space efficiency. The current algorithm also
appears to lose if the number of active paths exceeds IPFLOW_MAX (256),
in which case it wastes lots of time trying to figure out which cache
entry to drop.
We had run out of bits in the nfs mount flags, I have moved the internal

statfs(), but I don't know of anything that looks at them.
