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.

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

In case there's already a completion pending command, I.e., a ramrod

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
    'advertised' as appeared in the 'ethtool -a' output.

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.

Indication of a single completed packet, marked by txbbs_skipped

while next packet to be sent (after the wake up) may have multiple
TXBBs (LSO/TSO packets for example), causing overflow in queue followed
by WQE corruption and TX queue timeout.
Instead, wake the stopped queue only when there's enough room for the
worst case (maximum sized WQE) packet that we should need to handle after
the queue is opened again.
