This untested patch _should_ fix:
"(net de2104x) Kernel panic with de2104x tulip driver on boot"
http://bugzilla.kernel.org/show_bug.cgi?id=3156
But the bug submitter isn't responding. Same fix has been applied
to tulip.c (several years ago) and uli526x.c (Feb 2008) drivers.
[ The panic reported in the bug report was removed in a recently

This is a critical patch which adds a workaround for a HW bug. The patch
will limit the number of outstanding tx packets to 16. Otherwise, the HW
could send out packets with bad checksums.
The driver will still setup the tx packets into the ring, however, will
only set the Valid bit on 16 packets at a time.

The last change in the Tx queue stop mechanism opens a window
where the Tx queue might be stopped after pending credits
returned.
Tx credits are returned via a control message generated by the HW.
It returns tx credits on demand, triggered by a completion bit
set in selective transmit packet headers.
The current code can lead to the Tx queue stopped
with all pending credits returned, and the current frame
not triggering a credit return. The Tx queue will then never be
awaken.
The driver could alternatively request a completion for packets
that stop the queue. It's however safer at this point to go back
to the pre-existing behaviour.

This patch should resolve a problem that's troubled support for
some RNDIS peripherals. It seems to have boiled down to using a
variable to establish transfer size limits before it was assigned,
which caused those devices to fallback to a default "jumbogram"
mode we don't support. Fix by assigning it earlier for RNDIS.

Problem Description and Fix
---------------------------
When a pause packet(with destination as reserved Multicast address) is
received by the EMAC hardware to control the flow of frames being
transmitted by it, it is dropped by the hardware unless the reserved
Multicast address is hashed in to the GAHT[1-4] registers. This code fix
adds the default reserved multicast address to the GAHT[1-4] registers
in the EMAC(s) present on the chip. The flow control with Pause packets
will only work if the following register bits are programmed in EMAC:
EMACx_MR1[APP] = 1
EMACx_RMR[BAE] = 1
EMACx_RMR[MAE] = 1
Behavior that may be observed in a running system
-------------------------------------------------
A host transferring data from a PPC based system may send a Pause packet
to the PPC EMAC requesting it to slow down the flow of packets. If the
default reserved multicast MAC address is not programmed into the
GAHT[1-4] registers this Pause packet will be dropped by PPC EMAC and no
Flow Control will be done.

Add suspend/resume handlers to rt2x00rfkill to have it stop
the input-polldev and prevent it from calling rt2x00 during
suspend period. This could lead to a NULL pointer fault when
rt2x00 suspended, but polldev send a request, because
the csr_addr is NULL.
Also don't let the rfkill allocation/registration block

and continue as if nothing happened.

The gelic driver uses two net interfaces, one for ethernet and the
other for wireless. They share same MAC address and use 'eth' prefix
for the name.
As udev uses the MAC address to check uniqueness, this is
somewhat problematic. So change the prefix of the network interface
name for the wireless so that udev can have an easy way to distinguish
interfaces.

Some implementations of the hidden SSID APs emit beacons which have the zero
length SSID information element instead of SSID padded by null (\0) characters.
If the firmware of the PS3 wireless hardware meets these beacons, it abandons parsing
IEs. Thus guest OSes get the invalid scan information for the AP.
To work around this, ignore these scan informations from the list.

[IPV6]: Move nfheader_len into rt6_info
The dst member nfheader_len is only used by IPv6. It's also currently
creating a rather ugly alignment hole in struct dst. Therefore this patch
moves it from there into struct rt6_info.
Above patch changes the cache line alignment, especially member
__refcnt. I did a testing by adding 2 unsigned long pading before
lastuse, so the 3 members, lastuse/__refcnt/__use, are moved to next
cache line. The performance is recovered.
I created a patch to rearrange the members in struct dst_entry.
With Eric and Valdis Kletnieks's suggestion, I made finer arrangement.
1) Move tclassid under ops in case CONFIG_NET_CLS_ROUTE=y. So
sizeof(dst_entry)=200 no matter if CONFIG_NET_CLS_ROUTE=y/n. I
tested many patches on my 16-core tigerton by moving tclassid to
different place. It looks like tclassid could also have impact on
performance. If moving tclassid before metrics, or just don't move
tclassid, the performance isn't good. So I move it behind metrics.
2) Add comments before __refcnt.
On 16-core tigerton:
If CONFIG_NET_CLS_ROUTE=y, the result with below patch is about 18%
better than the one without the patch;
If CONFIG_NET_CLS_ROUTE=n, the result with below patch is about 30%
better than the one without the patch.
With 32bit 2.6.25-rc1 on 8-core stoakley, the new patch doesn't
introduce regression.
Thank Eric, Valdis, and David!

With TSO it was possible to send past the receiver window when the skb
to be sent was the last in the write queue while the receiver window
is the limiting factor. One can notice that there's a loophole in the
tcp_mss_split_point that lacked a receiver window check for the
tcp_write_queue_tail() if also cwnd was smaller than the full skb.
Noticed by Thomas Gleixner <tglx@linutronix.de> in form of "Treason
uncloaked! Peer ... shrinks window .... Repaired." messages (the peer
didn't actually shrink its window as the message suggests, we had just
sent something past it without a permission to do so).

Commit ce7663d84:
[NETFILTER]: nfnetlink_queue: don't unregister handler of other subsystem
changed nf_unregister_queue_handler to return an error when attempting to
unregister a queue handler that is not identical to the one passed in.
This is correct in case we really do have a different queue handler already
registered, but some existing userspace code always does an unbind before
bind and aborts if that fails, so try to be nice and return success in
that case.

0 exists
Similar to the nfnetlink_log problem, nfnetlink_queue incorrectly
returns -EPERM when binding or unbinding to an address family and
queueing instance 0 exists and is owned by a different process. Unlike
nfnetlink_log it previously completes the operation, but it is still
incorrect.

exists
When binding or unbinding to an address family, the res_id is usually set
to zero. When logging instance 0 already exists and is owned by a different
process, this makes nfunl_recv_config return -EPERM without performing
the bind operation.
Since no operation on the foreign logging instance itself was requested,
this is incorrect. Move bind/unbind commands before the queue instance
permissions checks.
Also remove an incorrect comment.

From: Andrew Schulman <andrex@alumni.utexas.net>
xt_time_match() in net/netfilter/xt_time.c in kernel 2.6.24 never
matches on Sundays. On my host I have a rule like
iptables -A OUTPUT -m time --weekdays Sun -j REJECT
and it never matches. The problem is in localtime_2(), which uses
r->weekday = (4 + r->dse) % 7;
to map the epoch day onto a weekday in {0,...,6}. In particular this
gives 0 for Sundays. But 0 has to be wrong; a weekday of 0 can never
match. xt_time_match() has
if (!(info->weekdays_match & (1 << current_time.weekday)))
return false;
and when current_time.weekday = 0, the result of the & is always
zero, even when info->weekdays_match = XT_TIME_ALL_WEEKDAYS = 0xFE.

Size of the netlink skb was wrongly computed because the formula was using
NLMSG_ALIGN instead of NLMSG_SPACE. NLMSG_ALIGN does not add the room for
netlink header as NLMSG_SPACE does. This was causing a failure of message
building in some cases.
On my test system, all messages for packets in range [8*k+41, 8*k+48] where k
is an integer were invalid and the corresponding packets were dropped.
