Currently, we allocate one page for the hardware DMA RSS indirection
table.  While the size is currently big enough for all chips, future
chip variations may support bigger sizes, so it is better to calculate

net: phy: Uninline PHY ethtool statistics

Now that we have introduced ethtool_phy_ops we can uninline those
operations and move them back into phy.c where they belong. Since those
functions are used by DSA, we need to continue exporting those symbols.

It might be possible to remove ndo_get_ethtool_phy_stats in a subsequent
patch since we could have DSA register its own ethtool_phy_ops instance
instead of overloading the ethtool_ops.

Linux Kernel Mentee: Remove Legacy Power Management.

The purpose of this patch series is to remove legacy power management callbacks
from smsc ethernet drivers.

The callbacks performing suspend() and resume() operations are still calling
pci_save_state(), pci_set_power_state(), etc. and handling the power management
themselves, which is not recommended.

The conversion requires the removal of the those function calls and change the
callback definition accordingly and make use of dev_pm_ops structure.

To ensure that the octeon MDIO driver has been loaded, the Cavium
ethernet drivers reference a dummy symbol in the MDIO driver. This
forces it to be loaded first. And this symbol has not been cleanly
implemented, resulting in warnings when build W=1 C=1.

Since device tree is being used, and a phandle points to the PHY on
the MDIO bus, we can make use of deferred probing. If the PHY fails to
connect, it should be because the MDIO bus driver has not loaded
yet. Return -EPROBE_DEFER so it will be tried again later.

Additionally, add a MODULE_SOFTDEP() to give user space a hint as to
what order it should load the modules.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^#

 \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

Alexander Lobakin says:

====================
net: qed/qede: W=1 C=1 warnings cleanup

This set cleans qed/qede build log under W=1 C=1 with GCC 8 and
sparse 0.6.2. The only thing left is "context imbalance -- unexpected
unlock" in one of the source files, which will be issued later during
the refactoring cycles.

The biggest part is handling the endianness warnings. The current code
often just assumes that both host and device operate in LE, which is
obviously incorrect (despite the fact that it's true for x86 platforms),
and makes sparse {s,m}ad.

The rest of the series is mostly random non-functional fixes
here-and-there.

Flow Dissector's keys are mostly Network / Big Endian. U{16,32}_MAX are
the same in either of byteorders, but let's make sparse happy with
wrapping them into noops.
