bridge: mdb: add support for extended attributes
This small set allows to extend the per mdb entry exported attributes,
before this set we had only a structure exported which couldn't be changed
because we would've broken user-space, after this we extend the attribute
that was used for the structure and add per-mdb entry attributes after the
struct has been added (see patch 02 for more details). Note that the reason
we can't simply add an attribute after MDBA_MDB_ENTRY_INFO is that current
users (e.g. iproute2) walk over the attribute list directly without
checking for the attribute type.
Patch 01 is a simple change to reduce one indentation level in order to
avoid over 80 char lines.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Currently mdb entries are exported directly as a structure inside
MDBA_MDB_ENTRY_INFO attribute, we can't really extend it without
breaking user-space. In order to export new mdb fields, I've converted
the MDBA_MDB_ENTRY_INFO into a nested attribute which starts like before
with struct br_mdb_entry (without header, as it's casted directly in
iproute2) and continues with MDBA_MDB_EATTR_ attributes. This way we
keep compatibility with older users and can export new data.
I've tested this with iproute2, both with and without support for the
added attribute and it works fine.
So basically we again have MDBA_MDB_ENTRY_INFO with struct br_mdb_entry
inside but it may contain also some additional MDBA_MDB_EATTR_ attributes
such as MDBA_MDB_EATTR_TIMER which can be parsed by user-space.
So the new structure is:
[MDBA_MDB] = {
[MDBA_MDB_ENTRY] = {
[MDBA_MDB_ENTRY_INFO]
[MDBA_MDB_ENTRY_INFO] { <- Nested attribute
struct br_mdb_entry <- nla_put_nohdr()
[MDBA_MDB_ENTRY attributes] <- normal netlink attributes
}
}
}

40GbE Intel Wired LAN Driver Updates 2016-02-19
This series contains updates to i40e/i40evf only.
Alex Duyck splits up the descriptor count function from the function that
stops the ring to have access to the descriptor count used for the data
portion of the frame. The rewrites the logic for how we determine if we
can transmit the frame or if it needs to be linearized. Place the checksum
close to TSO since they have a lot in common and it can help to reduce the
decision tree for how to handle the frame as the first check in TSO is to
see if checksumming is offloaded.
Carolyn adds functions to blink leds on devices using 10GBaseT PHY since
MAC registers used in other designs do not work in this device configuration.
Fixes an issue where a previously removed message has returned.
Kevin increases the timeout when checking GLGEN_RSTAT_DEVSTATE bit since
linking with particular PHY types, the amount of time it takes for the
GLGEN_RSTAT_DEVSTATE to be set increases greatly.
Neerav changes the receive queues to not wait to be disabled before DCB
has been reconfigured, like transmit queues.
Anjali adds new register definitions for programming the parser, flow
director and RSS blocks in the hardware.
Shannon adds the new opcodes and structures used for asking the firmware
to update receive control registers that need extra care when being

This patch is meant to rewrite the logic for how we determine if we can
transmit the frame or if it needs to be linearized.
The previous code for this function was using a mix of division and modulus
division as a part of computing if we need to take the slow path. Instead
I have replaced this by simply working with a sliding window which will
tell us if the frame would be capable of causing a single packet to span
several descriptors.
The logic for the scan is fairly simple. If any given group of 6 fragments
is less than gso_size - 1 then it is possible for us to have one byte
coming out of the first fragment, 6 fragments, and one or more bytes coming
out of the last fragment. This gives us a total of 8 fragments
which exceeds what we can allow so we send such frames to be linearized.
Arguably the use of modulus might be more exact as the approach I propose
may generate some false positives. However the likelihood of us taking much
of a hit for those false positives is fairly low, and I would rather not
add more overhead in the case where we are receiving a frame composed of 4K
pages.

Also in order to try and reduce unnecessary duplication of code I am moving
the slow-path portions of the code out of being inline calls so that we can
just jump to them and process them instead of having to build them into

40GbE Intel Wired LAN Driver Updates 2016-02-18
This series contains updates to i40e and i40evf only.
Alex Duyck provides all the patches in the series to update and fix the
drivers. Fixed the driver to drop the outer checksum offload on UDP
tunnels, since the issue is that the upper levels of the stack never
requested such an offload and it results in possible errors. Updates the
TSO function to just use u64 values, so we do not have to end up casting
u32 values. In the TSO path, factored out the L4 header offsets allowing
us to ignore the L4 header offsets when dealing with the L3 checksum and
length update. Consolidates all of the spots where we were updating
either the TCP or IP checksums in the TSO and checksum path into the TSO
function. Fixed two issues by adding support for IPv4 encapsulated in
IPv6, first issue was the fact that iphdr(skb)->protocol was being used to
test for the outer transport protocol which breaks IPv6 support. The second
was that we cleared the flag for v4 going to v6, but we did not take care
of txflags going the other way. Added support for IPv6 extension headers
in setting up the Tx checksum. Added exception handling to the Tx
checksum path so that we can handle cases of TSO where the frame is bad,
or Tx checksum where we did not recognize a protocol. Fixed a number of
issues to make certain that we are using the correct protocols when
parsing both the inner and outer headers of a frame that is mixed between
IPv4 and IPv6 for inner and outer. Updated the feature flags to reflect
the newly enabled/added features.
Sorry, no witty patch descriptions this time around, probably should
let Mitch help in writing patch descriptions for Alex. :-)

First we can assume the entire header is in the region pointed to by

Second, as a result of our first assumption, we can just call csum_partial

This patch defers writing to the Tx descriptor bits until we know we have

identified the type.
The advantage to this approach is that we can assemble values as we go
instead of having to try and kludge everything together all at once. As a
result we can significantly clean up the tunneling configuration for
instance as we can just do a pointer walk and do the math for the distance
between each set of points.
