* Fix matching of IPv6 state entries when the initial packet is a
sent to a multicast address. This includes not updating the address as
being fixed when a second (or further) such packet is seen before a reply.
* Disable code, for now, that limited how many ICMP packets could match a
state entry based on the number of real packets seen.
received packets in csum_flags in the packet header. Packets that are
forwarded over the bridge need to have csum_flags cleared before being
put on the output queue. Do so in bridge_enqueue().
Discussed with Jason Thorpe.
Fixes PR kern/27007 and the first part of PR kern/21831.
- Change the Tx:Rx on-chip RAM allocation ratio based on MTU:
=> 82547: > 8192 18K:22K, else 10K:30K
=> others: > 8192 24K:40K, else 16K:48K
Values derived from Linux driver.
- On the 82547, keep track of how much of the Tx FIFO has been used.
When in half-duplex mode, don't let packets wrap around the FIFO ring
buffer, because that causes the chip to croak. Detect this, stall the
Tx queue, use a timer to wait for the packets to drain from the Tx FIFO,
reset the internal FIFO pointers, and restart the Tx queue. Basic
algorithm (and some magic numbers) derived from FreeBSD and Linux drivers.
if ni == NULL and the operating mode was not "ad hoc" or "ad hoc
demo." That crashed the kernel. Now, if the operating mode is
not "ad hoc (demo)," and ni == NULL, return NULL right away.
Also, if ieee80211_dup_bss returns NULL, return NULL right away.
This doesn't fix a bug, but it makes clear how this works.
sense, since 1) the condition is quite normal condition and 2) there is
pool between us and uvm.
- Make the step of allocation possibility a bit seamless by moving the origin
of curve from 0 to lowater mark.
Simon told that this helps for interactive performance when there is heavy
disk activity in PR#27057.
disklabels nested inside an MBR "NetBSD" or "386BSD" partition (first
one found is considered authoritative for the disk), or in one of several
known locations for various NetBSD platforms. It can read native or other-
endian disklabels (code is there, but not tested).
If you want to play with this, exercise caution; you can't currently
mountroot on a wedge (setroot() needs some work). Enabled by the
DKWEDGE_METHOD_BSDLABEL kernel option.
all keymaps except the US english one can be removed from the kernel
with this option, which results in a space gain of about 10kB.
XXX it would be nice if we could strip down more kernel facilities
