Mediadetect is another name for the EDPD (energy detect power down).
This feature allows device to save extra power when no link is available.
PHY goes into the extreme power saving mode and only periodically wakes up
and checks for the link.
AQC devices has fixed check period of 6 seconds
The feature may increase linkup time.

A driver may refuse to enable VLAN filtering for any reason beyond what
the DSA framework cares about, such as:
- having tc-flower rules that rely on the switch being VLAN-aware
- the particular switch does not support VLAN, even if the driver does
(the DSA framework just checks for the presence of the .port_vlan_add
and .port_vlan_del pointers)
- simply not supporting this configuration to be toggled at runtime
Currently, when a driver rejects a configuration it cannot support, it
does this from the commit phase, which triggers various warnings in
switchdev.
So propagate the prepare phase to drivers, to give them the ability to
refuse invalid configurations cleanly and avoid the warnings.
Since we need to modify all function prototypes and check for the
prepare phase from within the drivers, take that opportunity and move
the existing driver restrictions within the prepare phase where that is
possible and easy.

1. Keep the code for the normal (non-error) flow at the lowest
indentation level. And use "goto drop" for all error handling.
2. Replace code that pads short Ethernet frames with a "__skb_pad" call.
3. Change "dev_kfree_skb" to "kfree_skb" in error handling code.
"kfree_skb" is the correct function to call when dropping an skb due to
an error. "dev_kfree_skb", which is an alias of "consume_skb", is for
dropping skbs normally (not due to an error).

clang static analysis reports this problem:

^~~~~~~~~~~~~~~
When mvneta_txq_sw_init() fails to alloc txq->tso_hdrs,
it frees without poisoning txq->buf. The error is caught
in the mvneta_setup_txqs() caller which handles the error
by cleaning up all of the txqs with a call to
mvneta_txq_sw_deinit which also frees txq->buf.
Since mvneta_txq_sw_deinit is a general cleaner, all of the
partial cleaning in mvneta_txq_sw_deinit()'s error handling
is not needed.

The variable "i" isn't initialized back correctly after the first loop
under the label inst_rollback gets executed.
The value of "i" is assigned to be option_count - 1, and the ensuing
loop (under alloc_rollback) begins by initializing i--.
Thus, the value of i when the loop begins execution will now become
i = option_count - 2.
Thus, when kfree(dst_opts[i]) is called in the second loop in this
order, (i.e., inst_rollback followed by alloc_rollback),
dst_optsp[option_count - 2] is the first element freed, and
dst_opts[option_count - 1] does not get freed, and thus, a memory
leak is caused.
This memory leak can be fixed, by assigning i = option_count (instead of
option_count - 1).

Currently, the driver will schedule RX ring reset when we get a buffer
error in the RX completion record. These RX buffer errors can be due
to normal out-of-buffer conditions or a permanent error in the RX
ring. Because the driver cannot distinguish between these 2
conditions, we assume all these buffer errors require reset.
This is very disruptive when it is just a normal out-of-buffer
condition. Newer firmware will now monitor the rings for the permanent
failure and will send a notification to the driver when it happens.
This allows the driver to reset only when such a notification is
received. In environments where we have predominently out-of-buffer
conditions, we now can avoid these unnecessary resets.

There is logic in the RX path to detect unexpected handles in the
RX completion. We'll print a warning and schedule a reset. The
next expected handle is then set to 0xffff which is guaranteed to
not match any valid handle. This will force all remaining packets in
the ring to be discarded before the reset. There can be hundreds of
these packets remaining in the ring and there is no need to print the
warnings for these forced errors.

On some older chips, it is necessary to do a reset when we get buffer
errors associated with an RX ring. These buffer errors may become
frequent if the RX ring underruns under heavy traffic. The current
code does a global reset of all reasources when this happens. This
works but creates a big disruption of all rings when one RX ring is
having problem. This patch implements a localized RX ring reset of
just the RX ring having the issue. All other rings including all
TX rings will not be affected by this single RX ring reset.
Only the older chips prior to the P5 class supports this reset.
Because it is not a global reset, packets may still be arriving
while we are calling firmware to reset that ring. We need to be
sure that we don't post any buffers during this time while the
ring is undergoing reset. After firmware completes successfully,
the ring will be in the reset state with no buffers and we can start
filling it with new buffers and posting them.

Ethtool manual stated that the tx-timer is the "the amount of time the
device should stay in idle mode prior to asserting its Tx LPI". The
previous implementation for "ethtool --set-eee tx-timer" sets the LPI TW
timer duration which is not correct. Hence, this patch fixes the
"ethtool --set-eee tx-timer" to configure the EEE LPI timer.
The LPI TW Timer will be using the defined default value instead of
"ethtool --set-eee tx-timer" which follows the EEE LS timer implementation.
Changelog V2
*Not removing/modifying the eee_timer.
*EEE LPI timer can be configured through ethtool and also the eee_timer
module param.
*EEE TW Timer will be configured with default value only, not able to be
configured through ethtool or module param. This follows the implementation
of the EEE LS Timer.

This consists of registering the array of parser error drops supported,

DPAA2 devices do not support controlling the action of independent
parser error traps, thus the .trap_action_set() callback just returns an

Via the OCELOT_MASK_MODE_REDIRECT flag put in the IS2 action vector, it
is possible to replace previous forwarding decisions with the port mask
installed in this rule.
I have studied Table 54 "MASK_MODE and PORT_MASK Combinations" from the
VSC7514 documentation and it appears to behave sanely when this rule is
installed in either lookup 0 or 1. Namely, a redirect in lookup 1 will
overwrite the forwarding decision taken by any entry in lookup 0.

The issue which led to the introduction of this check was that MAC_ETYPE
rules, such as filters on dst_mac and src_mac, would only match non-IP
frames. There is a knob in VCAP_S2_CFG which forces all IP frames to be
treated as non-IP, which is what we're currently doing if the user
requested a dst_mac filter, in order to maintain sanity.
But that knob is actually per IS2 lookup. And the good thing with
exposing the lookups to the user via tc chains is that we're now able to
offload MAC_ETYPE keys to one lookup, and IP keys to the other lookup.
So let's do that.

We were installing TCAM rules with the LOOKUP field as unmasked, meaning
that all entries were matching on all lookups. Now that lookups are
exposed as individual chains, let's make the LOOKUP explicit when
offloading TCAM entries.

VCAP ES0 is an egress VCAP operating on all outgoing frames.
This patch added ES0 driver to support vlan push action of tc filter.
Usage:
tc filter add dev swp1 egress protocol 802.1Q flower indev swp0 skip_sw \
vlan_id 1 vlan_prio 1 action vlan push id 2 priority 2

VCAP IS1 is a VCAP module which can filter on the most common L2/L3/L4
Ethernet keys, and modify the results of the basic QoS classification
and VLAN classification based on those flow keys.
There are 3 VCAP IS1 lookups, mapped over chains 10000, 11000 and 12000.
Currently the driver is hardcoded to use IS1_ACTION_TYPE_NORMAL half
keys.
Note that the VLAN_MANGLE has been omitted for now. In hardware, the
VCAP_IS1_ACT_VID_REPLACE_ENA field replaces the classified VLAN
(metadata associated with the frame) and not the VLAN from the header
itself. There are currently some issues which need to be addressed when
operating in standalone, or in bridge with vlan_filtering=0 modes,
because in those cases the switch ports have VLAN awareness disabled,
and changing the classified VLAN to anything other than the pvid causes
the packets to be dropped. Another issue is that on egress, we expect
port tagging to push the classified VLAN, but port tagging is disabled
in the modes mentioned above, so although the classified VLAN is
replaced, it is not visible in the packet transmitted by the switch.

For Ocelot switches, there are 2 ingress pipelines for flow offload
rules: VCAP IS1 (Ingress Classification) and IS2 (Security Enforcement).
IS1 and IS2 support different sets of actions. The pipeline order for a
packet on ingress is:
Basic classification -> VCAP IS1 -> VCAP IS2
Furthermore, IS1 is looked up 3 times, and IS2 is looked up twice (each
TCAM entry can be configured to match only on the first lookup, or only
on the second, or on both etc).
Because the TCAMs are completely independent in hardware, and because of
the fixed pipeline, we actually have very limited options when it comes
to offloading complex rules to them while still maintaining the same
semantics with the software data path.
This patch maps flow offload rules to ingress TCAMs according to a
predefined chain index number. There is going to be a script in
selftests that clarifies the usage model.
There is also an egress TCAM (VCAP ES0, the Egress Rewriter), which is
modeled on top of the default chain 0 of the egress qdisc, because it
doesn't have multiple lookups.

Since the mscc_ocelot_switch_lib is common between a pure switchdev and
a DSA driver, the procedure of retrieving a net_device for a certain
port index differs, as those are registered by their individual
front-ends.
Up to now that has been dealt with by always passing the port index to
the switch library, but now, we're going to need to work with net_device
pointers from the tc-flower offload, for things like indev, or mirred.
It is not desirable to refactor that, so let's make sure that the flower
offload core has the ability to translate between a net_device and a
port index properly.
