Checking the stack usage of my kernel, showed that ipw2200 had a few bad
offenders. This is on i386 32-bit:
0x00002876 ipw_send_associate: 544
0x000028ee ipw_send_associate: 544
0x000027dc ipw_send_scan_request_ext: 520
0x00002864 ipw_set_sensitivity: 520
0x00005eac ipw_set_rsn_capa: 520
The reason is the host_cmd structure is large (500 bytes). All other
functions currently using ipw_send_cmd() suffer from the same problem.
This patch introduces ipw_send_cmd_simple() for commands with no data
transfer, and ipw_send_cmd_pdu() for commands with a data payload and
makes the payload a pointer to the buffer passed in from the caller.
As an added bonus, the diffstat looks like this:
ipw2200.c | 260 +++++++++++++++++++++-----------------------------------------
ipw2200.h | 2
2 files changed, 92 insertions(+), 170 deletions(-)
and it shrinks the module a lot as well:
Before:
text data bss dec hex filename
75177 2472 44 77693 12f7d drivers/net/wireless/ipw2200.ko
After:

I can't really help with why restarts happen, but the following patch
greatly increases the likelihood that a firmware reload will succeed
afterward on my thinkpad. It addresses two issues. First, sysfs module
loading and hotplug are asynchronous, and as such file operations on the
"loading" and "data" files are racy when you load 2 firmwares in quick
succession. Second, the timeout for DMAing the firmware needs to scale
with the size of the firmware being loaded. That is, the watchdog needs
to be on throughput, not on time alone.
I no longer get the firmware load errors, though this is at best a hacky
workaround for a racy interface. (Obviously, this does nothing to address
the fatal errors in firmware which cause reloads; it just causes the
initial loading and the reloads to work more often.)

The ipw2100 driver misunderstood the parameter of txpower.
Tx Power off means turn off the radio, but the driver interpret it as
"can't set txpower". So when getting the txpower, it sets disabled=1 to
the iwconifg tool in managed mode. And the tool will display "Tx Power off"
when disabled=1.
Now, in managed mode, iwconfig will not show "TX Power" if the radio is not
switched off. It will only display "Tx Power off" only if the radio is killed.

Hi,
Below is a patch for the Large Receive Offload feature.
Please review and let us know your comments.
LRO algorithm was described in an OLS 2005 presentation, located at
ftp.s2io.com
user: linuxdocs
password: HALdocs
The same ftp site has Programming Manual for Xframe-I ASIC.
LRO feature is supported on Neterion Xframe-I, Xframe-II and
Xframe-Express 10GbE NICs.
Brief description:
The Large Receive Offload(LRO) feature is a stateless offload
that is complementary to TSO feature but on the receive path.
The idea is to combine and collapse(upto 64K maximum) in the
driver, in-sequence TCP packets belonging to the same session.
It is mainly designed to improve 1500 mtu receive performance,
since Jumbo frame performance is already close to 10GbE line
rate. Some performance numbers are attached below.
Implementation details:
1. Handle packet chains from multiple sessions(current default
MAX_LRO_SESSSIONS=32).
2. Examine each packet for eligiblity to aggregate. A packet is
considered eligible if it meets all the below criteria.
a. It is a TCP/IP packet and L2 type is not LLC or SNAP.
b. The packet has no checksum errors(L3 and L4).
c. There are no IP options. The only TCP option supported is timestamps.
d. Search and locate the LRO object corresponding to this
socket and ensure packet is in TCP sequence.
e. It's not a special packet(SYN, FIN, RST, URG, PSH etc. flags are not set).
f. TCP payload is non-zero(It's not a pure ACK).
g. It's not an IP-fragmented packet.
3. If a packet is found eligible, the LRO object is updated with
information such as next sequence number expected, current length
of aggregated packet and so on. If not eligible or max packets
reached, update IP and TCP headers of first packet in the chain
and pass it up to stack.
4. The frag_list in skb structure is used to chain packets into one
large packet.
Kernel changes required: None
Performance results:
Main focus of the initial testing was on 1500 mtu receiver, since this
is a bottleneck not covered by the existing stateless offloads.
There are couple disclaimers about the performance results below:
1. Your mileage will vary!!!! We initially concentrated on couple pci-x
2.0 platforms that are powerful enough to push 10 GbE NIC and do not
have bottlenecks other than cpu%; testing on other platforms is still
in progress. On some lower end systems we are seeing lower gains.
2. Current LRO implementation is still (for the most part) software based,
and therefore performance potential of the feature is far from being realized.
Full hw implementation of LRO is expected in the next version of Xframe ASIC.
Performance delta(with MTU=1500) going from LRO disabled to enabled:
IBM 2-way Xeon (x366) : 3.5 to 7.1 Gbps
2-way Opteron : 4.5 to 6.1 Gbps

Since get_settings() returns a signed int and it gets checked
for < 0 to catch an error, res should be a signed int too.

Make phy 0 actually be read, as it is not being right now as we have:
int mii_status = mdio_read(dev, phy, MII_BMSR);
int phyx = phy & 0x1f;
When we should have instead:
int phyx = phy & 0x1f;
int mii_status = mdio_read(dev, phyx, MII_BMSR);
so that when phy, in the end of the (phy = 1; phy <= 32...) loop gets
to 32 phyx gets to 0, i.e. we were reading at 32, when the intended
read was for 0.

On my latest laptop, I've had occasional PHY dead on wakeup from
sleep... the PHY would be totally unresponsive even to toggling the hard
reset line until the machine is powered down... Looking closely at the
code, I found some possible issues in the way we setup the MDIO lines
during suspend along with slight divergences from what Darwin does when
resetting it that may explain the problem. That patch change these and
the problem appear to be gone for me at least... I also fixed an mdelay
-> msleep while I was at it to the pmac feature code that is called
when toggling the PHY reset line since sungem doesn't call it in an
atomic context anymore.

Using the checksum value will be incorrect if the UDP packet has

*) mark as "EXPERIMENTAL" various items that either aren't very stable or
that are actively crashing the setup of users which don't really need them
(i.e. HIGHMEM and 3-level pagetables on x86 - nobody needs either,
everybody reports "I'm using it and getting trouble").
*) move net/Kconfig near to the rest of network configurations, and
drivers/block/Kconfig near "Block layer" submenu.
*) it's useless and doesn't work well to force NETDEVICES on and to disable
the prompt like it's done. Better remove the attempt, and change that to a
simple "default y if UML".
*) drop the warning about "report problems about HPPFS" - it's redundant
anyway, as that's the usual procedure, and HPPFS users are especially
technical (i.e. they know reporting bugs is _good_).

There are a couple of problems in the DMA setup code for skge.
* In the 64 bit case, it doesn't set the consistent mask.
* In the 32 bit case, the error check is backwards!
It likely will only be visible as a bug on 64 bit platforms.
