Mauro Carvalho Chehab c6fff4d3b2 docs: net: sja1105.rst: fix table format
There's a table there with produces two warnings when built
with Sphinx:

    Documentation/networking/dsa/sja1105.rst:91: WARNING: Block quote ends without a blank line; unexpected unindent.
    Documentation/networking/dsa/sja1105.rst:91: WARNING: Block quote ends without a blank line; unexpected unindent.

It will still produce a table, but the html output is wrong, as
it won't interpret the second line as the continuation for the
first ones, because identation doesn't match.

After the change, the output looks a way better and we got rid
of two warnings.

David S. Miller 70f3522614 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Three conflicts, one of which, for marvell10g.c is non-trivial and
requires some follow-up from Heiner or someone else.

The issue is that Heiner converted the marvell10g driver over to
use the generic c45 code as much as possible.

However, in 'net' a bug fix appeared which makes sure that a new
local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0
is cleared.

Vivien Didelot 9d490b4ee4 net: dsa: rename switch operations structure
Now that the dsa_switch_driver structure contains only function pointers
as it is supposed to, rename it to the more appropriate dsa_switch_ops,
uniformly to any other operations structure in the kernel.

No functional changes here, basically just the result of something like:
s/dsa_switch_driver *drv/dsa_switch_ops *ops/g

However keep the {un,}register_switch_driver functions and their
dsa_switch_drivers list as is, since they represent the -- likely to be
deprecated soon -- legacy DSA registration framework.

In the meantime, also fix the following checks from checkpatch.pl to
make it happy with this patch:

    CHECK: Comparison to NULL could be written "!ops"
    #403: FILE: net/dsa/dsa.c:470:
    +	if (ops == NULL) {

    CHECK: Comparison to NULL could be written "ds->ops->get_strings"
    #773: FILE: net/dsa/slave.c:697:
    +		if (ds->ops->get_strings != NULL)

    CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats"
    #824: FILE: net/dsa/slave.c:785:
    +	if (ds->ops->get_ethtool_stats != NULL)

    CHECK: Comparison to NULL could be written "ds->ops->get_sset_count"
    #835: FILE: net/dsa/slave.c:798:

    total: 0 errors, 0 warnings, 4 checks, 784 lines checked
