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.
v2:
* Remove the max/min validity checks from __mlxsw_sp_trap_policer_set()

Prepare an array of policer IDs to register with devlink and their
associated parameters.
The array is composed from both policers that are currently bound to
exposed trap groups and policers that are not bound to any trap group.
v2:
* Provide max/min rate/burst size when registering policers

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.

The QoS Policer Configuration Register (QPCR) is used to configure
hardware policers. Extend this register with following fields and
defines which will be used by subsequent patches:
1. Violate counter: reads number of packets dropped by the policer
2. Clear counter: to ensure we start counting from 0
3. Rate and burst size limits

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.

Register three dummy packet trap policers with devlink and implement
callbacks to change their parameters and read their counters.
This will be used later on in the series to test the devlink-trap
policer infrastructure.
v2:
* Remove check about burst size being a power of 2 and instead add a
debugfs knob to fail the operation
* Provide max/min rate/burst size when registering policers and remove
the validity checks from nsim_dev_devlink_trap_policer_set()

Add a separate set of PCS operations, which MAC drivers can use to
couple phylink with their associated MAC PCS layer. The PCS
operations include:
- pcs_get_state() - reads the link up/down, resolved speed, duplex
and pause from the PCS.
- pcs_config() - configures the PCS for the specified mode, PHY
interface type, and setting the advertisement.
- pcs_an_restart() - restarts 802.3 in-band negotiation with the
link partner
- pcs_link_up() - informs the PCS that link has come up, and the
parameters of the link. Link parameters are used to program the
PCS for fixed speed and non-inband modes.

Factor out mapping the tx skb to a new function rtl8169_tx_map(). This
allows to remove redundancies, and rtl8169_get_txd_opts1() has only
one user left, so it can be inlined.
As a result rtl8169_xmit_frags() is significantly simplified, and in
rtl8169_start_xmit() the code is simplified and better readable.
No functional change intended.

The qed_chain data structure was modified in
commit 1a4a69751f4d ("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.

This patch adds complete support for manipulating the L2 Policing Tables
from this switch. There are 45 table entries, one entry per each port
and traffic class, and one dedicated entry for broadcast traffic for
each ingress port.
Policing entries are shareable, and we use this functionality to support
shared block filters.
We are modeling broadcast policers as simple tc-flower matches on
dst_mac. As for the traffic class policers, the switch only deduces the
traffic class from the VLAN PCP field, so it makes sense to model this
as a tc-flower match on vlan_prio.
How to limit broadcast traffic coming from all front-panel ports to a
cumulated total of 10 Mbit/s:
tc qdisc add dev sw0p0 ingress_block 1 clsact
tc qdisc add dev sw0p1 ingress_block 1 clsact
tc qdisc add dev sw0p2 ingress_block 1 clsact
tc qdisc add dev sw0p3 ingress_block 1 clsact
tc filter add block 1 flower skip_sw dst_mac ff:ff:ff:ff:ff:ff \
action police rate 10mbit burst 64k
How to limit traffic with VLAN PCP 0 (also includes untagged traffic) to
100 Mbit/s on port 0 only:
tc filter add dev sw0p0 ingress protocol 802.1Q flower skip_sw \
vlan_prio 0 action police rate 100mbit burst 64k
The broadcast, VLAN PCP and port policers are compatible with one
another (can be installed at the same time on a port).

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.

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.

The PTP Hardware Clock (PHC) subsystem offers an API for configuring
programmable pins. User space sets or gets the settings using ioctls,
and drivers verify dialed settings via a callback. Drivers may also
query pin settings by calling the ptp_find_pin() method.
Although the core subsystem protects concurrent access to the pin
settings, the implementation places illogical restrictions on how
drivers may call ptp_find_pin(). When enabling an auxiliary function
via the .enable(on=1) callback, drivers may invoke the pin finding
method, but when disabling with .enable(on=0) drivers are not
permitted to do so. With the exception of the mv88e6xxx, all of the
PHC drivers do respect this restriction, but still the locking pattern
is both confusing and unnecessary.
This patch changes the locking implementation to allow PHC drivers to
freely call ptp_find_pin() from their .enable() and .verify()
callbacks.

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.

A recent commit e8937681797c ("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.

Enable the L3 driver's IPv4 address notifier to watch for events on qeth
devices that have been moved into a net namespace. We need to program
those IPs into the HW just as usual, otherwise inbound traffic won't
flow.

Calling queue_delayed_work concurrently with
destroy_workqueue might race to an unexpected outcome -
scheduled task after wq is destroyed or other resources
(like ptt_pool) are freed (yields NULL pointer dereference).
cancel_delayed_work prevents the race by cancelling
the timer triggered for scheduling a new task.

The KSZ9131 provides DLL controlled delays on RXC and TXC lines. This
patch makes use of those delays. The information which delays should
be enabled or disabled comes from the interface names, documented in
ethernet-controller.yaml:
rgmii: Disable RXC and TXC delays
rgmii-id: Enable RXC and TXC delays
rgmii-txid: Enable only TXC delay, disable RXC delay
rgmii-rxid: Enable onlx RXC delay, disable TXC delay

This patch adds new netlink attribute to allow a user to (optionally)
specify the desired offload mode immediately upon MACSec link creation.
Separate iproute patch will be required to support this from user space.
