Intel Wired LAN Driver Updates 2023-08-07 (ice)
This series contains updates to ice driver only.
Wojciech allows for LAG interfaces to be used for bridge offloads.
Marcin tracks additional metadata for filtering rules to aid in proper
differentiation of similar rules. He also renames some flags that
do not entirely describe their representation.
Karol and Jan add additional waiting for firmware load on devices that
require it.
Przemek refactors RSS implementation to clarify/simplify configurations.

Add fdir_fltr_lock locking in unprotected places.
The change in iavf_fdir_is_dup_fltr adds a spinlock around a loop which
iterates over all filters and looks for a duplicate. The filter can be
removed from list and freed from memory at the same time it's being
compared. All other places where filters are deleted are already
protected with spinlock.
The remaining changes protect adapter->fdir_active_fltr variable so now
all its uses are under a spinlock.

1) Few cleanups
2) Dynamic completion EQs
The driver creates completion EQs for all vectors directly on driver
load, even if those EQs will not be utilized later on.
To allow more flexibility in managing completion EQs and to reduce the
memory overhead of driver load, this series will adjust completion EQs
creation to be dynamic. Meaning, completion EQs will be created only
when needed.
Patch #1 introduces a counter for tracking the current number of
completion EQs.
Patches #2-6 refactor the existing infrastructure of managing completion
EQs and completion IRQs to be compatible with per-vector
allocation/release requests.
Patches #7-8 modify the CPU-to-IRQ affinity calculation to be resilient
in case the affinity is requested but completion IRQ is not allocated yet.
Patch #9 function rename.
Patch #10 handles the corner case of SF performing an IRQ request when no
SF IRQ pool is found, and no PF IRQ exists for the same vector.
Patch #11 modify driver to use dynamically allocate completion EQs.

In externel_lb process, the hns3 driver call napi_disable()
first, then the reset happen, then the restore process of the
externel_lb will fail, and will not call napi_enable(). When
doing externel_lb again, napi_disable() will be double call,
cause a deadlock of rtnl_lock().
This patch use the HNS3_NIC_STATE_DOWN state to protect the
calling of napi_disable() and napi_enable() in externel_lb
process, just as the usage in ndo_stop() and ndo_start().

Change the new (unreleased) SO_PEERPIDFD sockopt to return ENODATA
rather than ESRCH if a socket type does not support remote peer-PID
queries.
Currently, SO_PEERPIDFD returns ESRCH when the socket in question is
not an AF_UNIX socket. This is quite unexpected, given that one would
assume ESRCH means the peer process already exited and thus cannot be
found. However, in that case the sockopt actually returns EINVAL (via
pidfd_prepare()). This is rather inconsistent with other syscalls, which
usually return ESRCH if a given PID refers to a non-existant process.
This changes SO_PEERPIDFD to return ENODATA instead. This is also what
SO_PEERGROUPS returns, and thus keeps a consistent behavior across
sockopts.
Note that this code is returned in 2 cases: First, if the socket type is
not AF_UNIX, and secondly if the socket was not yet connected. In both
cases ENODATA seems suitable.

commit 914d6f44fc ("RISC-V: only iterate over possible CPUs in ISA
string parser") changed riscv_fill_hwcap() from iterating over CPU DT
nodes to iterating over logical CPU IDs. Since this function runs long
before cpu_dev_init() creates CPU devices, it hits the fallback path in
of_cpu_device_node_get(), which itself iterates over the DT nodes,
searching for a node with the requested CPU ID. (Incidentally, this
makes riscv_fill_hwcap() now take quadratic time.)
riscv_fill_hwcap() passes a logical CPU ID to of_cpu_device_node_get(),
which uses the arch_match_cpu_phys_id() hook to translate the logical ID
to a physical ID as found in the DT.
arch_match_cpu_phys_id() has a generic weak definition, and RISC-V
provides a strong definition using cpuid_to_hartid_map(). However, the
RISC-V specific implementation is located in arch/riscv/kernel/smp.c,
and that file is only compiled when SMP is enabled.
As a result, when SMP is disabled, the generic definition is used, and
riscv_isa gets initialized based on the ISA string of hart 0, not the
boot hart. On FU740, this means has_fpu() returns false, and userspace
crashes when trying to use floating-point instructions.
Fix this by moving arch_match_cpu_phys_id() to a file which is always
compiled.

Fix the following warning:
drivers/net/ethernet/broadcom/bnxt/bnxt_dcb.c: In function ‘bnxt_hwrm_queue_cos2bw_cfg’:
cc1: error: writing 12 bytes into a region of size 1 [-Werror=stringop-overflow ]

drivers/net/ethernet/broadcom/bnxt/bnxt_hsi.h:6045:17: note: destination object ‘unused_0’ of size 1
6045 | u8 unused_0;
Fix it by modifying struct hwrm_queue_cos2bw_cfg_input to use an array
of sub struct similar to the previous patch. This will eliminate the
pointer arithmetc to calculate the destination pointer passed to
memcpy().

Fix the following warning:

__read_overflow2_field(q_size_field, size);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Modify the FW interface defintion of struct hwrm_queue_cos2bw_qcfg_output
to use an array of sub struct for the queue1 to queue7 fields. Note that
the layout of the queue0 fields are different and these are not part of
the array. This makes the code much cleaner by removing the pointer
arithmetic for memcpy().

The "loc" value comes from the user and it can be negative leading to an
an array underflow when we check "priv->net_filters[loc].claimed". Fix
this by changing the type to u32.

net: fs_enet: Driver cleanup
Over the years, platform and driver initialisation have evolved into
more generic ways, and driver or platform specific stuff has gone
away, leaving stale objects behind.
This series aims at cleaning all that up for fs_enet ethernet driver.
