Merge branch 'for-davem' of git://git./linux/kernel/git/bwh/sfc-next

Ben Hutchings says:

====================
Some bug fixes that should go into 3.7:

1. Fix oops when removing device with SR-IOV enabled.  (This regression
was introduced by the last set of changes, so the fix does not need to
be applied to any earlier kernel versions.)
2. Fix firmware structure field lookup bug that resulted in missing
sensor information.
3. Fix bug that makes self-test do very little in some configurations.
4. Fix the numbering of ethtool RX flow steering filters to reflect the
real hardware priorities.

sfc: Fix the reported priorities of different filter types

Each RX filter table contains filters with two different levels of
specificity: TCP/IPv4 and UDP/IPv4 filters match the local address and
port and optionally the remote address and port; Ethernet filters
match the local address and optionally the VID.  The more specific
filters always override less specific filters within the same table,
and should be numbered accordingly.

This field should have been initialised to efx_channel_dummy_op_void

flexcan: disable bus error interrupts for the i.MX28

Due to a bug in most Flexcan cores, the bus error interrupt needs
to be enabled. Otherwise we don't get any error warning or passive
interrupts. This is _not_ necessary for the i.MX28 and this patch
disables bus error interrupts if "berr-reporting" is not requested.
This avoids bus error flooding, which might harm, especially on
low-end systems.

To handle such quirks of the Flexcan cores, a hardware feature flag
has been introduced, also replacing the "hw_ver" variable. So far
nobody could tell what Flexcan core version is available on what
Freescale SOC, apart from the i.MX6Q and P1010, and which bugs or
features are present on the various "hw_rev".

ipv6: del unreachable route when an addr is deleted on lo

When an address is added on loopback (ip -6 a a 2002::1/128 dev lo), two routes
are added:
 - one in the local table:

 - one the in main table (for the prefix):
    unreachable 2002::1 dev lo  proto kernel  metric 256  error -101

When the address is deleted, the route inserted in the main table remains
because we use rt6_lookup(), which returns NULL when dst->error is set, which
is the case here! Thus, it is better to use ip6_route_lookup() to avoid this
kind of filter.

    vs. DCB priorities.
 2. iSCSI - not all packets were completed on a forward channel.

 4. Fixed false parity reported in CAM memories when operating near -5%
    on the 1.0V core supply.
 5. ETS default settings are set to fairness between traffic classes
    (rather than strict priority), and uses the same chip receive buffer
    configuration for both PFC and pause.

tg3: Disable multiple TX rings by default due to hardware flaw

Simple round-robin hardware TX scheduling can cause starvation of TX rings
with small packets when other TX rings have large TSO or jumbo packets.

In the simplest case, consider 2 TCP streams running in opposite
directions.  The TSO TX traffic will hash to one ring and the ACKs for the
incoming data on a different TCP connection will hash to a different TX
ring.  The hardware fetches one complete TSO packet (up to 64K data)
before servicing the other TX ring.  When it gets to the other TX ring, it
will only fetch one packet (64-byte ACK packet in this case).  After that,
it will switch back to the 1st ring filled with more TSO packets.  Because
only one ACK can go out roughly every 500 usec in this case, the incoming
data rate becomes very low.

Update version to 3.125.

mwifiex: send firmware initialization commands synchronously

The driver will send some commands to firmware during the
initialization. Currently these commands are sent asynchronously,
which means that we firstly insert all of them to a pre-allocated
command queue, and then start to process them one by one. The
command queue will soon be exhausted if we keep adding new
initialization commands.

This issue can be resolved by sending initialization commands
synchronously because each command is consumed and the buffer is
recycled before queuing next command.
