Merge branch 'fix-a-couple-recent-instances-of-wincompatible-function-pointer-types-strict-from-mode_get-implementations'

Nathan Chancellor says:

====================
Fix a couple recent instances of -Wincompatible-function-pointer-types-strict from ->mode_get() implementations

This series fixes a couple of instances of
-Wincompatible-function-pointer-types-strict that were introduced by a
recent series that added a new type of ops, struct dpll_device_ops,
along with implementations of the callback ->mode_get() that had a
mismatched mode type.

This warning is not currently enabled for any build but I am planning on
submitting a patch to add it to W=1 to prevent new instances of the
warning from popping up while we try and fix the existing instances in
other drivers.

This series is based on current net-next but if they need to go into
individual maintainer trees, please feel free to take the patches
individually.

A bulk transfer of the USB may contain many packets. And, the total
number of the packets in the bulk transfer may be more than budget.

Originally, only budget packets would be handled by napi_gro_receive(),
and the other packets would be queued in the driver for next schedule.

This patch would break the loop about getting next bulk transfer, when
the budget is exhausted. That is, only the current bulk transfer would
be handled, and the other bulk transfers would be queued for next
schedule. Besides, the packets which are more than the budget in the
current bulk trasnfer would be still queued in the driver, as the
original method.

In addition, a bulk transfer wouldn't contain more than 400 packets, so
the check of queue length is unnecessary. Therefore, I replace it with
WARN_ON_ONCE().

The recent support for DPLL introduced by commit 8a3a565f ("ice: add
admin commands to access cgu configuration") and commit d7999f5e ("ice:
implement dpll interface to control cgu") broke linking the ice driver if
CONFIG_PTP_1588_CLOCK=n:

ld: vmlinux.o: in function `ice_init_feature_support':

ld: vmlinux.o: in function `ice_dpll_init':
(.text+0x8953d5): undefined reference to `ice_get_cgu_rclk_pin_info'

The first commit broke things by calling functions in
ice_init_feature_support that are compiled as part of ice_ptp_hw.o,
including:

* ice_is_phy_rclk_present
* ice_is_clock_mux_present_e810t
* ice_is_cgU_present

The second commit continued the break by calling several CGU functions
defined in ice_ptp_hw.c in the DPLL code.
Because the ice_dpll.c file is compiled unconditionally, it will not
link when CONFIG_PTP_1588_CLOCK=n.

It might be possible to break this dependency and expose those functions
without CONFIG_PTP_1588_CLOCK, but that is not clear to me.

For the DPLL case, simply compile ice_dpll.o only when we have
CONFIG_PTP_1588_CLOCK. Add stub no-op implementation of ice_dpll_init() and
ice_dpll_uninit() when CONFIG_PTP_1588_CLOCK=n into ice_dpll.h

The other functions are part of checking the netlist to see if hardware
features are enabled. These checks don't really belong in ice_ptp_hw.c, and
make more sense as part of the ice_common.c file. We already have
ice_is_gps_in_netlist() in ice_common.c which is doing a similar check.

Move the functions into ice_common.c and rename them to have the similar
postfix of "in_netlist()" to be more expressive of what they are actually
checking.

This also makes the ice_find_netlist_node only called from within
ice_common.c, so its safe to mark it static and stop declaring it in the
ice_common.h header as well.

Newer versions of firmware will pre-reserve 1 VNIC for every possible
PF and VF function.  Update the driver logic to take this into account
when assigning VNICs to the VFs.  These pre-reserved VNICs for the
inactive VFs should be subtracted from the global pool before
assigning them to the active VFs.

Not doing so may cause discrepancies that ultimately may cause some VFs to

the section DPLL SUBSYSTEM in MAINTAINERS and includes a file entry to the
non-existing file 'include/net/dpll.h'.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference. Looking at the file stat of the commit above, this entry
clearly intended to refer to 'include/linux/dpll.h'.

Adjust this header file entry in DPLL SUBSYSTEM.

This change adds a sysctl to opt-out of RFC4862 section 5.5.3e's valid
lifetime derivation mechanism.

RFC4862 section 5.5.3e prescribes that the valid lifetime in a Router
Advertisement PIO shall be ignored if it less than 2 hours and to reset
the lifetime of the corresponding address to 2 hours. An in-progress
6man draft (see draft-ietf-6man-slaac-renum-07 section 4.2) is currently
looking to remove this mechanism. While this draft has not been moving
particularly quickly for other reasons, there is widespread consensus on
section 4.2 which updates RFC4862 section 5.5.3e.

The iAVF txrx hotpath code has several functions that are marked as
"static inline" in the iavf_txrx.c file. This use of inline is frowned
upon in the netdev community and explicitly marked as something to avoid
in the Linux coding-style document (section 15).

Even though these functions are only used once, it is expected that GCC
is smart enough to decide when to perform function inlining where
appropriate without the "hint".

./scripts/bloat-o-meter is showing zero difference with this changes.

As the comment in struct rtnl_link_stats64, rx_dropped should not
include packets dropped by the device due to buffer exhaustion.
They are counted in rx_missed_errors, procfs folds those two counters
together.

Add rx_missed_errors for buffer exhaustion, rx_missed_errors corresponds
to rx_discards, rx_dropped corresponds to rx_discards_other.

Documentation fixes for dpll subsystem

Here is a mini docs fixes for dpll subsystem. The fixes are all code
block-related.

This series is triggered because I was emailed by kernel test robot,
alerting htmldocs warnings (see patch [1/2]).

====================
introduce DEFINE_FLEX() macro

Add DEFINE_FLEX() macro, that helps on-stack allocation of structures
with trailing flex array member.
Expose __struct_size() macro which reads size of data allocated
by DEFINE_FLEX().

Accompany new macros introduction with actual usage,
in the ice driver - hence targeting for netdev tree.

Obvious benefits include simpler resulting code, less heap usage,
less error checking. Less obvious is the fact that compiler has
more room to optimize, and as a whole, even with more stuff on the stack,
we end up with overall better (smaller) report from bloat-o-meter:
add/remove: 8/6 grow/shrink: 7/18 up/down: 2211/-2270 (-59)
(individual results in each patch).
