Using mod_delayed_work() allows to simplify handling delayed work and
removes the need for the sync parameter in phy_trigger_machine().
Also introduce a helper phy_queue_state_machine() to encapsulate the
low-level delayed work calls. No functional change intended.

In preparation for unconditionally enabling TX and RX checksum offloads,
refactor bcm_sysport_set_features() a bit such that
__netdev_update_features() during register_netdev() can make sure that
features are correctly programmed during network device registration.
Since we can now be called during register_netdev() with clocks gated,
we need to temporarily turn them on/off in order to have a successful
register programming.
We also move the CRC forward setting read into
bcm_sysport_set_features() since priv->crc_fwd matters while turning on
RX checksum offload, that way we are guaranteed they are in sync in case
we ever add support for NETIF_F_RXFCS at some point in the future.

netlink: extended attribute validation
This adds further netlink attribute validation:
* min/max/range validation
* validation through a custom function pointer
This is useful to
* reduce boilerplate code in command handling code, if attributes
are used commonly across different commands
* get more extended ACK error messages/attribute pointers
* ensure attributes are valid even when ignored
(though this might be a problem when converting existing code)
Changes since v1:
* split off validate_type from type and use that for min/max/range
and function; this is better because the range is limited to the
range of s16 and so things like "u16 with minimum value 1" couldn't
be expressed earlier
* add macros for this, e.g. NLA_POLICY_MIN(NLA_U16, 1) for the case
mentioned in the previous bullet
Using this pretty much in all places where applicable in nl80211
reduces the code size there by about 1.8KiB, with just a minimal
code increase in lib/nlattr.o.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Add the ability to have an arbitrary validation function attached
to a netlink policy that doesn't already use the validation_data
pointer in another way.
This can be useful to validate for example the content of a binary
attribute, like in nl80211 the "(information) elements", which must
be valid streams of "u8 type, u8 length, u8 value[length]".
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
Without further bloating the policy structs, we can overload
the `validation_data' pointer with a struct of s16 min, max
and use those to validate ranges in NLA_{U,S}{8,16,32,64}
attributes.
It may sound strange to validate NLA_U32 with a s16 max, but
in many cases NLA_U32 is used for enums etc. since there's no
size benefit in using a smaller attribute width anyway, due
to netlink attribute alignment; in cases like that it's still
useful, particularly when the attribute really transports an
enum value.
Doing so lets us remove quite a bit of validation code, if we
can be sure that these attributes aren't used by userspace in
places where they're ignored today.
To achieve all this, split the 'type' field and introduce a
new 'validation_type' field which indicates what further
validation (beyond the validation prescribed by the type of
the attribute) is done. This currently allows for no further
validation (the default), as well as min, max and range checks.

Build bitmap equivalents of the u32 values at runtime, and have the

we don't want a driver to modify them. So mark them __ro_after_init.

100GbE Intel Wired LAN Driver Updates 2018-10-01
This series contains updates to ice driver only.
Anirudh provides several changes to "prep" the driver for upcoming
features. Specifically, the functions that are used for PF VSI/netdev
setup will also be used in SR-IOV support and to allow the reuse of
these functions, code needs to move.
Dave provides the only other change in the series, updates the driver to
protect the reset patch in its entirety. This is done by adding the
various bit checks to determine if a reset is scheduled/initiated and
whether it came from the software or firmware.

Currently, there is no bit, or set of bits, that protect the entirety
of the reset path.
If the reset is originated by the driver, then the relevant
one of the following bits will be set when the reset is scheduled:
__ICE_PFR_REQ
__ICE_CORER_REQ
__ICE_GLOBR_REQ
This bit will not be cleared until after the rebuild has completed.
If the reset is originated by the FW, then the first the driver knows of
it will be the reception of the OICR interrupt. The __ICE_RESET_OICR_RECV
bit will be set in the interrupt handler. This will also be the indicator
in a SW originated reset that we have completed the pre-OICR tasks and
have informed the FW that a reset was requested.
To utilize these bits, change the function:
ice_is_reset_recovery_pending()
to be:
ice_is_reset_in_progress()
The new function will check all of the above bits in the pf->state and
will return a true if one or more of these bits are set.

We can report checksum unnecessary also when the L3 checksum
flag on the cqe is set and there's no L4 header.

Increased the amount of channels the representors can open to be the
amount of CPUs. The default amount opened remains one.
Used the standard NIC netdev functions to:
* Set RSS params when building the representors' params.
* Setup an indirect TIR and RQT for the representors upon
initialization.
* Create a TTC flow table for the representors' indirect TIR (when
creating the TTC table, mlx5e_set_ttc_basic_params() is not called,
in order to avoid setting the inner_ttc param, which is not needed).
Added ethtool control to the representors for setting and querying
the amount of open channels. Additionally, included logic in the
representors' ethtool set channels handler which controls a
representor's vport rx rule, so that if there is one open channel
the rx rule steers traffic to the representor's direct TIR, whereas
if there is more than one channel, the rx rule steers traffic to the
new TTC flow table.

Towards enabling RSS for the vport representors, expose the functions for
querying the rss hash key size and indirection table size via ethtool.
