* [net-next 07/13] ixgbe: Reduce Rx header size to what is actually used

From: Alexander Duyck <alexander.h.duyck@intel.com>
The recent changes to netdev_alloc_skb actually make it so that the size of
the buffer now actually has a more direct input on the truesize. So in
order to make best use of the piece of a page we are allocated I am
reducing the IXGBE_RX_HDR_SIZE to 256 so that our truesize will be reduced
by 256 bytes as well.
This should result in performance improvements since the number of uses per
page should increase from 4 to 6 in the case of a 4K page. In addition we
should see socket performance improvements due to the truesize dropping
to less than 1K for buffers less than 256 bytes.

* [net-next 08/13] ixgbe: Use num_tcs.pg_tcs as upper limit for TC when checking based on UP
From: Jeff Kirsher @ 2012-07-21 23:08 UTC (permalink / raw)

In-Reply-To: <1342912142-11130-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Alexander Duyck <alexander.h.duyck@intel.com>
This change makes it so the function ixgbe_dcb_get_tc_from_up will use the
num_tcs.pg_tcs to determine the starting value for determining a traffic
class based on a user priority. The main motivation for this change is to
address possible bad configurations in which more TCs worth of data are
populated then there are actual TCs. By limiting this value we can at
least make certain we are not providing a map with values that are out of
range.
As a result any user priorities that are setup in the configuration with a
traffic class mapping higher than what the hardware supports will be
reported as being on TC 0.

* [net-next 09/13] ixgbe: fix RAR entry counting for generic and fdb_add()
From: Jeff Kirsher @ 2012-07-21 23:08 UTC (permalink / raw)
To: davem; +Cc: John Fastabend, netdev, gospo, sassmann, Jeff Kirsher
In-Reply-To: <1342912142-11130-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: John Fastabend <john.r.fastabend@intel.com>
Do RAR entry accounting correctly so that errors are reported and
promisc mode is set correctly when the number of entries exceeds
the hardware limits.
This can happen with many macvlan devices attached to the PF or
by adding many fdb entries in SR-IOV modes.
Also this includes a small refactor to fdb_add() to avoid having so
many nested if/else statements after adding a check for the number
or RAR entries.
The max entries for the PF is currently 16 we allow 15 additional
entries to account for the defined MAC.

This change makes it so that we can use 1TC DCB in the case of MSI and
legacy interrupts. The advantage to this is that it allows us to fully
support FCoE w/ DCB instead of having to drop to link flow control only
when using these interrupt modes.

* [net-next 13/13] igb: reset PHY in the link_up process to recover PHY setting after power down.
From: Jeff Kirsher @ 2012-07-21 23:09 UTC (permalink / raw)
To: davem; +Cc: Akeem G. Abodunrin, netdev, gospo, sassmann, Jeff Kirsher
In-Reply-To: <1342912142-11130-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: "Akeem G. Abodunrin" <akeem.g.abodunrin@intel.com>
There was a previous patch to resolve issue with 82576 losing PHY setting
after PHY power down. However that previous implementation triggered speed
mismatch and occasional link lost. Now, this patch resolves both initial
PHY setting and speed mismatch issues.

'Screen-scraping' the output of administrative tools is not good
practice. It may be the best you can do when writing a shell script,
but for a C program it's generaly less reliable and often more difficult
than using the underlying C API.

OK, got it. At this point, I guess we should enhance the patch to use
the values plugged into the IPv4 arp table at the time IPoIB is loaded,
with arp_tbl being exported its easy to achieve. This would allow users
to use non-default values by the ipoib neigh handling logic. In a later
step, we need to see if/how to allow ipoib to use the already existing
sysctl entries, makes sense?
Or.

Dave,
I have been running your routing removal patches for the past 3 days
(upgraded yesterday to latest set including the 17th patch you sent in
response to Eric's comment) and have not seen any issues (crashes
etc).
I used the kbench_mod module in net_test_tools for testing. Averaging
after 16 runs (with 4 samples in each run), I get the following for
output route lookups
(ip_route_output_key):
with route-removal patches: average of 544 cycles with min and max
of 511 and 721
without patches: (commit fa0afcd10 ) : average of 211 cycles with
min and max of 196 and 266
Apart from time spent in fib_table_lookup(), it seems time is also
spent in check_leaf(). I assume this is expected behavior.
Here are 2 sample perf outputs (I have appended the kbench outputs to
each file)
With patches applied:

* [PATCH RFC] tcp: use seqlock for all cached tcp_metrics
From: Julian Anastasov @ 2012-07-22 9:44 UTC (permalink / raw)
To: netdev
The ability to reclaim existing cache entries
requires metrics to be accessed with additional seqlock.
fastopen_cache tried to provide such locking for its values
but there is always the risk to access reclaimed entry.
So, we add global metrics_seqlock and two macros to
access metrics for read/write purposes. The macros are not
checkpatch friendly but with capital letters and no gotos in
the code we avoid additional level of indentation.
We provide access structure, initialized according to
the socket type with information about the hash bucket, dst, etc.
We also fix some problems:
- tcpm_stamp was not updated in tcpm_check_stamp when tcpm_suck_dst
was called, move the update into tcpm_suck_dst, so that we do not
call it infinitely on every next cache hit
- in tcp_tw_remember_stamp we incorrectly checked tw instead of tm,
it can lead to oops if the cached entry is not found

Open questions:
- is it safe to upgrade a seqlock reader to writer? May be
it is a good idea to provide such method seqlock_is_upgraded
in include/linux/seqlock.h. In our case it can safe 1 of the 3
lookups that we do in write mode.

Hi,
Shlomo Pongratz from Mellanox took a look on the patch, and we'd like
to clarify with you something - OTOH you mention EEH (Extended Error
Handling) error recovery which is a PPC related term mentioned in
Documentation/powerpc/eeh-pci-error-recovery.txt, but OTHO you've
implemented callbacks mentioned in the AER (Advanced Error Reporting)
doc of Documentation/PCI/pcieaer-howto.txt, is there anything in the
code you added which maybe implicitly assumes PPC arch?
Or.

What kernel are you see the issue one?
I believe this is fixed in net-next already:
commit 122bb046bcfb8f3d2d94d9f7f6b74da187a740f2
Author: Jiri Pirko <jpirko@redhat.com>
Date: Tue Jun 26 06:52:45 2012 +0000
team: fix team_adjust_ops with regard to enabled ports
team_adjust_ops should check for enabled ports, not all ports.
This may lead to division by zero. This patch fixes this.

Ben,
Based on the input I have gotten, the consensus appears to be to have external
scripts to both GET and SET IP related configuration information. So, the KVP
daemon will need to parse information returned from these external distro specific
scripts (on the GET side). While I agree with you that it is good to use C APIs, I currently
have the implementation using the "ip" command and it appears to be quite simple.
Furthermore, given that the information I need to pass back to the host needs to be
appropriately formatted (based on host specified format), I suspect using the "ip" command
may actually simplify the code.
Regards,
K. Y

* net-next compilation failure since 76ff5cc9
From: Richard Cochran @ 2012-07-22 16:21 UTC (permalink / raw)
To: netdev; +Cc: Jiri Pirko, David S. Miller
Without CONFIG_RPS, net-next fails to compile with
CC net/core/rtnetlink.o
/linux/net/core/rtnetlink.c: In function ‘rtnl_fill_ifinfo’:
/linux/net/core/rtnetlink.c:895: error: ‘struct net_device’ has no member named ‘num_rx_queues’
make[3]: *** [net/core/rtnetlink.o] Error 1
Looks like this was caused by
76ff5cc9 rtnl: allow to specify number of rx and tx queues on device creation
Not sure how to fix.

This series updates the ethtool code for four drivers that recently
add the skb_tx_timestamp hook. Since these drivers now support
software transmit time stamps, let us also advertise this via ethtool.

From: Mikhail Peselnik <peselnik@gmail.com>

Signed-off-by: Mikhail Peselnik <peselnik@gmail.com>
Tested-by: Mikhail Peselnik <peselnik@gmail.com>

Now with proper sign-offs and right people in cc.
plusb driver (drivers/net/usb/plusb.c) doesn't recognize PL2501 chip.
Since PL2501 uses the same code as PL2301/PL2302 (PL2501 works in
compatibility mode with PL2301/PL2302), the fix is trivial and
attached as a patch.
Just to note: the patch is not mine, it can be found here and there on
Internet.
I've tested the patch and it works great.
Thank you.
