100GbE Intel Wired LAN Driver Updates 2018-09-27

This series contains fixes to the ice driver only.

Jake fixes a potential crash due to attempting to access the mutex which
is already destroyed.  Fix this by using rq.count and sq.count to
determine if the queue was initialized.  Fixed the current logic for
checking the firmware version to properly handle situations when
firmware major/minor versions differ and when the branch version
differs.

Bruce replaces a memcpy() with a direct assignment, which is preferred.
Also updated the branding strings and device ids supported by the
driver.  Fixed the "ethtool -G" command in the driver, which was always
returning EINVAL when changing the descriptor ring size.

Brett update and clarified code comments.

Anirudh updates the driver to ensure we query the firmware for the
transmit scheduler node information before adding it to the driver
database, to ensure we have the current information.  Also update the
"get capabilities" command to get device and function capabilities.

netlink: nested policy validation

This adds nested policy validation, which lets you specify the
nested attribute type, e.g. NLA_NESTED with sub-policy, or the
new NLA_NESTED_ARRAY with sub-sub-policy.

Changes in v2:
 * move setting the bad attr pointer/message into validate_nla()
 * remove the recursion patch since that's no longer needed
 * simply skip the generic bad attr pointer/message setting in
   case of nested nla_validate() failing since that could fail
   only due to validate_nla() failing inside, which already sets
   the extack information

Changes in v3:
 * fix NLA_REJECT to have an error message if none is in policy
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Sometimes nested netlink attributes are just used as arrays, with
the nla_type() of each not being used; we have this in nl80211 and
e.g. NFTA_SET_ELEM_LIST_ELEMENTS.

Add the ability to validate this type of message directly in the
policy, by adding the type NLA_NESTED_ARRAY which does exactly
this: require a first level of nesting but ignore the attribute
type, and then inside each require a second level of nested and
validate those attributes against a given policy (if present).

Note that some nested array types actually require that all of
the entries have the same index, this is possible to express in
a nested policy already, apart from the validation that only the
one allowed type is used.
Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Now that we have a validation_data pointer, and the len field in
the policy is unused for NLA_NESTED, we can allow using them both
to have nested validation. This can be nice in code, although we
still have to use nla_parse_nested() or similar which would also
take a policy; however, it also serves as documentation in the
policy without requiring a look at the code.
Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This unifies the code between nla_parse() which sets the bad
attribute pointer and an error message, and nla_validate()
which only sets the bad attribute pointer.

It also cleans up the code for NLA_REJECT and paves the way
for nested policy validation, as it will allow us to easily
skip setting the "generic" message without any extra args
like the **error_msg now, just passing the extack through is
now enough.

While at it, remove the unnecessary label in nla_parse().

rx_mini_pending was set to an incorrect value. This was causing EINVAL to
always be returned to 'ethtool -G'. The driver does not support mini or
jumbo rings so the respective settings should be zero.

Also, change the valid range of the number of descriptors in the rings to
make the code simpler and easier for users to understand (this removes the
valid settings of 8 and 16). Add a system log message indicating when the
number is rounded-up from what the user specifies with the 'ethtool -G'
command (i.e. when it is not a multiple of 32), and update the log message
when a user-provided value is out of range to also indicate the stride.

We have MAX_FW_API_VER_BRANCH, MAX_FW_API_VER_MAJOR, and
MAX_FW_API_VER_MINOR that we use in ice_controlq.h to test when a
firmware version is newer than expected. This is currently tested by
comparing each field separately. Thus, we compare the branch field
against the MAX_FW_API_VER_BRANCH, and so forth.

This means that currently, if we suppose that the max firmware version
is defined as 0.2.1, i.e.

Then firmware 0.1.3 will fail to load. This is because the minor version
3 is greater than the max minor version 1.

This is not intuitive, because of the notion that increasing the major
firmware version to 2 should mean any firmware version with a major
version is less than 2 should be considered older than 2...

In order to allow both 0.2.1 and 0.1.3 to load, you would have to define
the "max" firmware version as 0.2.3.. It is possible that such
a firmware version doesn't even exist yet!

Fix this by replacing the current logic with an updated check that
behaves as follows:

First, we check the major version. If it is greater than the expected
version, then we prevent driver load. Additionally, a warning message is
logged to indicate to the system administrator that they need to update
their driver. This is now the only case where the driver will refuse to
load.

Second, if the major version is less than the expected version, we log
an information message indicating the NVM should be updated.

Third, if the major version is exact, we'll then check the minor
version. If the minor version is more than two versions less than
expected, we log an information message indicating the NVM should be
updated. If it is more than two versions greater than the expected
version, we log an information message that the driver should be
updated.

To support this, the ice_aq_ver_check function needs its signature
updated to pass the HW structure. Since we now pass this structure,
there is no need to pass the firmware API versions separately.
