Intel Wired LAN Driver Updates 2015-06-26

This series contains fixes for igb, e1000e and i40evf.

Todd disables IPv6 extension header processing due to a hardware errata
and bumps the driver version.

Yanir provides six fixes for e1000e.  First is a fix for a locking issue
where we were not always taking the pci_bus_sem semaphore all the time
when calling pci_disable_link_state_locked(), so fix the code to only call
pci_disable_link_state_locked() when the semaphore has been acquired,
otherwise call pci_disable_link_state().  A previous fix for i219 where
the hardware prevented ULP entry caused EEE in Sx not the be enabled, so
modify the code flow that allows both ULP and EEE in Sx.  Fix an issue
when running 10/100 full duplex on i219 where CRC errors were occurring
by increasing the IPG from 8 to 0xC as per the hardware developers.
Fix a data corruption issue found on some platforms by increasing the
minimum gap between the PHY FIFO read and write pointers.  Fix i219,
which does not require the K1 workaround for LPT devices.

Mitch provides a i40evf fix for a panic when changing MTU.  Down was
requesting queue disables, but then exited immediately without waiting
for the queues to actually be disabled.  This could allow any function
called after i40evf_down() to run immediately, including i40evf_up(),
and causes a memory leak.  Fixed the issue by removing the whole
reinit_locked function which allows for the driver to handle the state
changes by requesting reset from the periodic timer.  The second fix
resolves an issue where RSS was being configured as though it is using
the maximum number of queue.  This can cause the device to drop a lot
of receive traffic, as the packets get assigned to non-functional queues.
This is resolved by only configuring RSS with the number of active queues.

As some C45 10G PHYs(e.g. Cortina CS4315/CS4340 PHY) have
zero Devices In package, current driver can't get correct
devices_in_package value by non-zero Devices In package.
so let's probe more with zero Devices In package to support
more C45 PHYs.

Not all silicon implementations of the Freescale FEC hardware module
have the RACC (Receive Accelerator Function) register, so we should not
be trying to access it on those that don't. Currently none of the ColdFire
based parts with a FEC have it.

Support for RACC was introduced by commit 4c09eed9 ("net: fec: Enable imx6
enet checksum acceleration"). A fix was introduced in commit d1391930
("net: fec: Fix build for MCF5272") that disables its use on the ColdFire
M5272 part, but it doesn't fix the general case of other ColdFire parts.

To fix we create a quirk flag, FEC_QUIRK_HAS_RACC, and check it before
working with the RACC register.

In commit 1f66d161
("tipc: introduce starvation free send algorithm")
we introduced a counter per priority level for buffers
in the link backlog queue. We also introduced a new
function tipc_link_purge_backlog(), to reset these
counters to zero when the link is reset.

Unfortunately, we missed to call this function when
the broadcast link is reset, with the result that the
values of these counters might be permanently skewed
when new nodes are attached. This may in the worst case
lead to permananent, but spurious, broadcast link
congestion, where no broadcast packets can be sent at
all.

We fix this bug with this commit.

Removing the whole reinit_locked function is the best way
to go about this, and allows for the driver to handle the

Due to FW constraints, driver must make sure that transmitted SKBs will
not be too fragmented, or in the case that they are - that each 'window'
of fragments passed to the FW would contain at least an mss worth of data.

For encapsultaed packets the calculation is wrong, since it ignores the
inner headers in the calculation of the headers' length.
This could lead to a FW assertion in case of a too-fragmented encapsulated
packet.

Since driver statistics flow access MACs and those might reset during
link re-configurations, when we're about to change link properties we
have to make sure that statistics are not operational.
Statisics would be re-enabled [i.e., gathering of statistics would
re-commence] once physical link is achieved again.

Since driver employs a link-flap avoidance scheme, there are scenarios
where driver will receive no indication that the new link is up, and
as a result the statistics would not be re-enabled.

Preventing LFA from working in such cases would guarantee that we'll
always receive such indications and thus will fix statistics gathering.

The scratchpad is a shared block between all functions of a given device.
Due to HW limitations, we can't properly close its parity notifications
to all functions on legal flows.
E.g., it's possible that while taking a register dump from one function
a parity error would be triggered on other functions.

Today driver doesn't consider this parity as a 'real' parity unless its
being accompanied by additional indications [which would happen in a real
parity scenario]; But it does print notifications for such events in the
system logs.

This eliminates such prints - in case of real parities driver would have
additional indications; But if this is the only signal user will not even
see a parity being logged in the system.

Each time a flow finishes reads from the classification shadow
configuration in the driver, that flow would check for pending commands
and pass them to FW if possible.
In case there's already a completion pending command, I.e., a ramrod
that has been sent to the FW and is yet to be completed while said flow
tries to configure the pending command we would get a false error message
in logs [and panic if SOE was used for driver compilation] since the
command could not have been completed.

This prevents said print [and panic]; The pending command will be sent by

This fixes several issues relating to asymmetric configuration:
 1. When user requests to disable TX, the local-device needs to
    advertise both PAUSE and ASM_DIR, but to avoid transmitting pause
    frames. In the 578xx, it would ignore the TX disable.

 2. When user advertises RX-only, ASM_DIR was advertised instead of
    PAUSE/ASM_DIR.

 3. When changing mode, the advertised PAUSE/ASM_DIR was not cleared
    before setting new one, so disabling RX or TX had no impact on the

We use spinlock to access a single flag. We can avoid spin_locks by using
atomic variable and atomic_cmpxchg(). Use atomic_cmpxchg to set the flag
for idle to poll. And a simple atomic_set to unlock (set idle from poll).

In napi poll, if gro is enabled, we call napi_gro_receive() to deliver the
packets. Before we call napi_complete(), i.e while re-polling, if low
latency busy poll is called, we use netif_receive_skb() to deliver the packets.
At this point if there are some skb's held in GRO, busy poll could deliver the
packets out of order. So we call napi_gro_flush() to flush skbs before we
move the napi poll to idle.
