d12d846821 mlxsw: spectrum_trap: Switch to use correct packet trap group
Some packet traps are currently exposed to user space as being member of
"l3_drops" trap group, but internally they are member of a different
group.

Switch these traps to use the correct group so that they are all subject
to the same policer, as exposed to user space.

Set the trap priority of packets trapped due to loopback error during
routing to the lowest priority. Such packets are not routed again by the
kernel and therefore should not mask other traps (e.g., host miss) that
should be routed.

Register supported packet trap policers with devlink and implement
callbacks to change their parameters and read their counters.

Prevent user space from passing invalid policer parameters down to the
device by checking their validity and communicating the failure via an
appropriate extack message.

03484e49e7 mlxsw: spectrum: Track used packet trap policer IDs
During initialization the driver configures various packet trap groups
and binds policers to them.

Currently, most of these groups are not exposed to user space and
therefore their policers should not be exposed as well. Otherwise, user
space will be able to alter policer parameters without knowing which
packet traps are policed by the policer.

Use a bitmap to track the used policer IDs so that these policers will
not be registered with devlink in a subsequent patch.

f9f54392d2 devlink: Add packet trap group parameters support
Packet trap groups are used to aggregate logically related packet traps.
Currently, these groups allow user space to batch operations such as
setting the trap action of all member traps.

In order to prevent the CPU from being overwhelmed by too many trapped
packets, it is desirable to bind a packet trap policer to these groups.
For example, to limit all the packets that encountered an exception
during routing to 10Kpps.

Allow device drivers to bind default packet trap policers to packet trap
groups when the latter are registered with devlink.

The next patch will enable user space to change this default binding.

8063f761cd qed: Fix use after free in qed_chain_free
The qed_chain data structure was modified in
commit 1a4a69751f ("qed: Chain support for external PBL") to support
receiving an external pbl (due to iWARP FW requirements).
The pages pointed to by the pbl are allocated in qed_chain_alloc
and their virtual address are stored in an virtual addresses array to
enable accessing and freeing the data. The physical addresses however
weren't stored and were accessed directly from the external-pbl
during free.

Destroy-qp flow, leads to freeing the external pbl before the chain is
freed, when the chain is freed it tries accessing the already freed
external pbl, leading to a use-after-free. Therefore we need to store
the physical addresses in additional to the virtual addresses in a
new data structure.

c672412f61 ionic: remove lifs on fw reset
When the FW RESET event comes to the driver from the firmware,
or the fw_status goes to 0 (stopped) or to 0xff (no PCI
connection), then shut down the driver activity.  This event
signals a FW upgrade where we need to quiesce all operations and
wait for the FW to restart.  The FW will continue the update
process once it sees all the LIFs are reset.  When the update
process is done it will set the fw_status back to RUNNING.
Meanwhile, the heartbeat check continues and when the fw_status
is seen as set to running we can restart the driver operations.

49d3b49367 ionic: disable the queues on link down
When the link goes down, we need to disable the queues on the
NIC in addition to stopping the netdev stack.  This lets the
FW know that the driver has stopped queue activity, and then
the FW can do internal reconfiguration work, whether actually
Link related, or for other internal FW needs.  To do this,
we pull out the queue enable and disable from ionic_open()
and ionic_stop() so they can be used by other routines.

To help keep things sane, we swap the queue enables so that
the rx queue and its napi are enabled before the tx queue
which rides on the rx queues napi.

We also drop the ionic_lif_quiesce() as it doesn't do anything
more than what the queue disable has already taken care of.

6838a35a45 net/mlx5: Use a separate work queue for fib event handling
In VF lag mode when remove the bonding module without bring down the
bond device first, we could potentially have circular dependency when we
unload IB devices and also handle fib events:
1. The bond work starts first;
2. The "modprobe -rv bonding" process tries to release the bond device,
   with the "pernet_ops_rwsem" lock hold;
3. The bond work blocks in unregister_netdevice_notifier() and waits for
the lock because fib event came right before;
4. The kernel fib module tries to free all the fib entries by broadcasting
   the "FIB_EVENT_NH_DEL" event;
5. Upon the fib event this lag_mp module holds the fib lock and queue a
   fib work.
So:
   bond work -> modprobe task -> kernel fib module -> lag_mp -> bond work

Today we either reload IB devices in roce lag in nic mode or either handle
fib events in switchdev mode, but a new feature could change that we'll
need to reload IB devices also in switchdev mode so this is a future proof
fix as one may not notice this later.

41b145024c mlx4: fix "initializer element not constant" compiler error
A recent commit e893768179 ("devlink: prepare to support region
operations") used the region_cr_space_str and region_fw_health_str
variables as initializers for the devlink_region_ops structures.

This can result in compiler errors:
drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: error: initializer
element is not constant
   .name = region_cr_space_str,
           ^
drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: note: (near
initialization for ‘region_cr_space_ops.name’)
drivers/net/ethernet/mellanox//mlx4/crdump.c:50:10: error: initializer
element is not constant
   .name = region_fw_health_str,

The variables were made to be "const char * const", indicating that both
the pointer and data were constant. This was enough to resolve this on
recent GCC (gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1) for this author).

Unfortunately this is not enough for older compilers to realize that the
variable can be treated as a constant expression.

Fix this by introducing macros for the string and use those instead of
the variable name in the region ops structures.

DEV_GMII:MAC_CFG_STATUS:MAC_MAXLEN_CFG field MAX_LEN, which in turn
limits the size of frames that can be received.

Special accounting needs to be done for the DSA CPU port (NPI port in
hardware terms). The NPI port configuration needs to be held inside the
private ocelot structure, since it is now accessed from multiple places.

2e8c339b49 r8169: fix PHY driver check on platforms w/o module softdeps
On Android/x86 the module loading infrastructure can't deal with
softdeps. Therefore the check for presence of the Realtek PHY driver
module fails. mdiobus_register() will try to load the PHY driver
module, therefore move the check to after this call and explicitly
check that a dedicated PHY driver is bound to the PHY device.

e1da9618b7 mlxsw: core_acl: Avoid defining static variable in header file
The static array 'mlxsw_afk_element_infos' in 'core_acl_flex_keys.h' is
copied to each file that includes the header, but not all use it. This
results in the following warnings when compiling with W=1:

drivers/net/ethernet/mellanox/mlxsw//core_acl_flex_keys.h:76:44:
warning: ‘mlxsw_afk_element_infos’ defined but not used
[-Wunused-const-variable=]

One way to suppress the warning is to mark the array with
'__maybe_unused', but another option is to remove it from the header
file entirely.

Change 'struct mlxsw_afk_element_inst' to store the key to the array
('element') instead of the array value keyed by 'element'. Adjust the
different users accordingly.

8262e6f9b1 net: ks8851-ml: Fix IO operations, again
This patch reverts 5829210483 ("net: ks8851-ml: Fix 16-bit IO operation")
and edacb098ea ("net: ks8851-ml: Fix 16-bit data access"), because it
turns out these were only necessary due to buggy hardware. This patch adds
a check for such a buggy hardware to prevent any such mistakes again.

While working further on the KS8851 driver, it came to light that the
KS8851-16MLL is capable of switching bus endianness by a hardware strap,
EESK pin. If this strap is incorrect, the IO accesses require such endian
swapping as is being reverted by this patch. Such swapping also impacts
the performance significantly.

Hence, in addition to removing it, detect that the hardware is broken,
report to user, and fail to bind with such hardware.

Fixes: 5829210483 ("net: ks8851-ml: Fix 16-bit IO operation")
