Thanks for getting this all applied.  Our validation team is now testing 
the ixgbe patches with your version of ethtool and if I hear about any 
other bugs I might have introduced I will let you know.

* [PATCH] vmxnet3: Fix inconsistent LRO state after initialization
From: Thomas Jarosch @ 2011-05-16 16:28 UTC (permalink / raw)
  To: netdev; +Cc: Shreyas Bhatewara

During initialization of vmxnet3, the state of LRO
gets out of sync with netdev->features.

This leads to very poor TCP performance in a IP forwarding
setup and is hitting many VMware users.

Simplified call sequence:
1. vmxnet3_declare_features() initializes "adapter->lro" to true.

2. The kernel automatically disables LRO if IP forwarding is enabled,
so vmxnet3_set_flags() gets called. This also updates netdev->features.

3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still
set to true and LRO gets enabled again, even though
netdev->features shows it's disabled.

Fix it by updating "adapter->lro", too.


The private vmxnet3 adapter flags are scheduled for removal
in net-next, see commit a0d2730c9571aeba793cb5d3009094ee1d8fda35
"net: vmxnet3: convert to hw_features".

Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6.

Thanks for finding this. Vyatta ended up changing the default of adapter->lro
to workaround just this problem

Oh well, a table lookup is even faster...

Plus, the only users of the return value use it to feed "int"
return values of functions.  F.e. net/core/neighbour.c's use
in neightbl_fill_parms().

I don't see this as being any better or worse, and we should
just leave the return value alone.

First, you are missing a proper "Signed-off-by: " tag in your
patch submissions.

Second, you should not do this because now the lines after the
first won't have the default loglevel prepended.

I think this should just be left alone, and you should properly
mark your netconsole logs so that you can discern which machine
the individual messages come from so you can piece them together
properly if you need to.

I'm not taking patches which are against some random atom-linux tree,
you have to make your patches against the current upstream sources

This doesn't work.

The sysfs file will still be there before the uevent, so any
process can go in there, and see the inconsistent state.

Hmm, perhaps the printks can at least be grouped per line?

* [PATCH net-next-2.6 v2] ipv4: more compliant RFC 3168 support
From: Eric Dumazet @ 2011-05-16 18:37 UTC (permalink / raw)
  To: Stefanos Harhalakis; +Cc: David Miller, netdev
In-Reply-To: <1305566204.2898.49.camel@edumazet-laptop>

Commit 6623e3b24a5e (ipv4: IP defragmentation must be ECN aware) was an
attempt to not lose "Congestion Experienced" (CE) indications when
performing datagram defragmentation.

Stefanos Harhalakis raised the point that RFC 3168 requirements were not
completely met by this commit.

In particular, we MUST detect invalid combinations and eventually drop
illegal frames.

makes sense, so we can add the qp type here.

Or.

I don't know about this.

The usb_set_intfdata() calls at cdc_ncm_bind() time are unconditional,
and are performed regardless of whether ->data_claimed or
->control_claimed are set.

So conditionalizing the setting of them to NULL here doesn't seem
right at all.

I'm not applying this patch.
