VF's attempt to delete vlan 0 when a port vlan is configured is harmless
in this case pf driver just does nothing. If vf will try to remove
other vlans when a port vlan is configured it will still produce error
as before.

TX MDD events reported on the PF are the result of the
PF misconfiguring a descriptor and not because of "bad actions"
by anything else. No need to reset now because if it
results in a Tx hang, the Tx hang check will take care of it.

This patch changes the driver behavior when detecting a VF MDD event.
It now disables the VF after one event, which indicates a hw detected
problem in the VF. Before this change, the PF would allow a couple of
events before doing the reset.

Ethernet flow control:
The switch MAC does not consume, nor does it emit pause frames. It
simply forwards them as any other Ethernet frame (and since the DMAC is,
per IEEE spec, 01-80-C2-00-00-01, it means they are filtered as
link-local traffic and forwarded to the CPU, which can't do anything
useful with them).
Duplex:
There is no duplex setting in the SJA1105 MAC. It is known to forward
traffic at line rate on the same port in both directions. Therefore it
must be that it only supports full duplex.

Resetting the switch at runtime is currently done while changing the
vlan_filtering setting (due to the required TPID change).
But reset is asynchronous with packet egress, and the switch core will
not wait for egress to finish before carrying on with the reset
operation.
As a result, a connected PHY such as the BCM5464 would see an
unterminated Ethernet frame and start to jabber (repeat the last seen
Ethernet symbols - jabber is by definition an oversized Ethernet frame
with bad FCS). This behavior is strange in itself, but it also causes
the MACs of some link partners (such as the FRDM-LS1012A) to completely
lock up.
So as a remedy for this situation, when switch reset is required, simply
inhibit Tx on all ports, and wait for the necessary time for the
eventual one frame left in the egress queue (not even the Tx inhibit
command is instantaneous) to be flushed.

If STP is active, this setting is applied on bridged ports each time an
Ethernet link is established (topology changes).
Since the setting is global to the switch and a reset is required to
change it, resets are prevented if the new callback does not change the
value that the hardware already is programmed for.

VLAN filtering cannot be properly disabled in SJA1105. So in order to
emulate the "no VLAN awareness" behavior (not dropping traffic that is
tagged with a VID that isn't configured on the port), we need to hack
another switch feature: programmable TPID (which is 0x8100 for 802.1Q).
We are reprogramming the TPID to a bogus value which leaves the switch
thinking that all traffic is untagged, and therefore accepts it.
Under a vlan_filtering bridge, the proper TPID of ETH_P_8021Q is
installed again, and the switch starts identifying 802.1Q-tagged
traffic.

Documentation/devicetree/bindings/net/ethernet.txt is confusing because
it says what the MAC should not do, but not what it *should* do:
* "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC
should not add an RX delay in this case)
The gap in semantics is threefold:
1. Is it illegal for the MAC to apply the Rx internal delay by itself,
and simplify the phy_mode (mask off "rgmii-rxid" into "rgmii") before
passing it to of_phy_connect? The documentation would suggest yes.
1. For "rgmii-rxid", while the situation with the Rx clock skew is more
or less clear (needs to be added by the PHY), what should the MAC
driver do about the Tx delays? Is it an implicit wild card for the
MAC to apply delays in the Tx direction if it can? What if those were
already added as serpentine PCB traces, how could that be made more
obvious through DT bindings so that the MAC doesn't attempt to add
them twice and again potentially break the link?
3. If the interface is a fixed-link and therefore the PHY object is
fixed (a purely software entity that obviously cannot add clock
skew), what is the meaning of the above property?
So an interpretation of the RGMII bindings was chosen that hopefully
does not contradict their intention but also makes them more applied.
The SJA1105 driver understands to act upon "rgmii-*id" phy-mode bindings
if the port is in the PHY role (either explicitly, or if it is a
fixed-link). Otherwise it always passes the duty of setting up delays to
the PHY driver.
The error behavior that this patch adds is required on SJA1105E/T where
the MAC really cannot apply internal delays. If the other end of the
fixed-link cannot apply RGMII delays either (this would be specified
through its own DT bindings), then the situation requires PCB delays.
For SJA1105P/Q/R/S, this is however hardware supported and the error is
thus only temporary. I created a stub function pointer for configuring
delays per-port on RXC and TXC, and will implement it when I have access
to a board with this hardware setup.
Meanwhile do not allow the user to select an invalid configuration.

Currently only the (more difficult) first generation E/T series is
supported. Here the TCAM is only 4-way associative, and to know where
the hardware will search for a FDB entry, we need to perform the same
hash algorithm in order to install the entry in the correct bin.
On P/Q/R/S, the TCAM should be fully associative. However the SPI
command interface is different, and because I don't have access to a
new-generation device at the moment, support for it is TODO.

This structure was used intensively for machine specific values
when DT was not used. Since the removal of AVR32 from the kernel,
this structure is only used for passing clocks from PCI macb wrapper, all
other fields being 0.
All other known platforms use DT.
Remove the leftovers but make sure that PCI macb still works as
expected by using default values:
- phydev->irq is set to PHY_POLL by mdiobus_alloc()
- mii_bus->phy_mask is cleared while allocating it
- bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found
in DT.
This simplifies driver probe path and particularly phy handling.

When the state of rep was introduced, it was also designed to prevent
duplicate unloading of the same rep. Considering the following two
flows when an eswitch manager is at switchdev mode with n VF reps loaded.
+--------------------------------------+--------------------------------+
| cpu-0 | cpu-1 |
| -------- | -------- |
| mlx5_ib_remove | mlx5_eswitch_disable_sriov |
| mlx5_ib_unregister_vport_reps | esw_offloads_cleanup |
| mlx5_eswitch_unregister_vport_reps | esw_offloads_unload_all_reps |
| __unload_reps_all_vport | __unload_reps_all_vport |
+--------------------------------------+--------------------------------+
These two flows will try to unload the same rep. Per original design,
once one flow unloads the rep, the state moves to REGISTERED. The 2nd
flow will no longer needs to do the unload and bails out. However, as
read and write of the state is not atomic, when 1st flow is doing the
unload, the state is still LOADED, 2nd flow is able to do the same
unload action. Kernel crash will happen.
To solve this, driver should do atomic test-and-set for the state. So
that only one flow can change the rep state from LOADED to REGISTERED,
and proceed to do the actual unloading.
Since the state is changing to atomic type, all other read/write should
be atomic action as well.

The check of legal vport is to ensure the vport number falls between
0 and total number of vports. Along with the introduction of uplink
rep, enabled vports are not consecutive any more.
Therefore, rely on the eswitch vport getter function to check if it's
a valid vport.
As the getter function relies on eswitch, add the check of vport
group manager and validation the presence of eswitch structure.
Remove the redundant check in the function calls.
Since the vport array will be allocated once eswitch is initialized
and will be kept alive if eswitch presents, no need to protect it with
the state lock.

With unlocked TC it is possible to have spurious deletes and inserts of
same filter. TC layer needs drivers to always return error when flow
insertion failed in order to correctly calculate "in_hw_count" for each
filter. Fix mlx5e_configure_flower() to return -EEXIST when TC tries to
insert a filter that is already provisioned to the driver.

Current ConnectX HW is unable to perform VLAN pop in TX path and VLAN
push on RX path. To workaround that limitation untagged packets are
tagged with VLAN ID 0x000 (priority tag) and pop/push actions are
replaced by VLAN re-write actions (which are supported by the HW).
Replace TC VLAN pop action with a VLAN priority tag header rewrite.

Current ConnectX HW is unable to perform VLAN pop in TX path and VLAN
push on RX path. As a workaround, untagged packets are tagged with
VID 0x000 allowing pop/push actions to be exchanged with VLAN rewrite
actions.
Use the ingress ACL table, preceding the FDB, to push VLAN 0x000 ID tag
for untagged packets and the egress ACL table, succeeding the FDB, to
pop VLAN 0x000 ID tag.

Hardware requires that all TIRs that steer traffic to the same RQ
should share identical tunneled_offload_en value.
For that, the tunneled_offload_en bit should be set/unset (according to
the HW capability) for all TIRs', not only the ones dedicated for
tunneled (inner) traffic.

This commit introduces support for the "Drop" action in classification
offload. This corresponds to the "-1" action with ethtool -N.
This is achieved using the color marking actions available in the C2
engine, which associate a color to a packet. These colors can be either
Green, Yellow or Red, Red meaning that the packet should be dropped.
Green and Yellow colors are interpreted by the Policer, which isn't
supported yet.
This method of dropping using the Classifier is different than the
already existing early-drop features, such as VLAN filtering and MAC
UC/MC filtering, which are performed during the Parsing step, and
therefore take precedence over classification actions.
