The stmmac has the possibility to automatically strip the padding/FCS for IEEE
802.3 type frames. This feature is enabled conditionally. Therefore, the stmmac
receive path has to have a determination logic whether the FCS has to be
stripped in software or not.
In fact, for DSA this ACS feature is disabled and the determination logic
doesn't check for it properly. For instance, when using DSA in combination with
an older stmmac (pre version 4), the FCS is not stripped by hardware or software
which is problematic.
So either add another check for DSA to the fast path or simply disable ACS
feature completely. The latter approach has been chosen, because most of the
time the FCS is stripped in software anyway and it removes conditionals from the
receive fast path.

MACsec driver need to distinguish to which offload device the MACsec
is target to, in order to handle them correctly.
This can be done by attaching a metadata_dst to a SKB with a SCI,
when there is a match on MACsec rule.
To achieve that, there is a map between fs_id to SCI, so for each RX SC,
there is a unique fs_id allocated when creating RX SC.
fs_id passed to device driver as metadata for packets that passed Rx
MACsec offload to aid the driver to retrieve the matching SCI.

Rx flow steering consists of two flow tables (FTs).
The first FT (crypto table) have one default miss rule so non MACsec
offloaded packets bypass the MACSec tables.
All others flow table entries (FTEs) are divided to two equal groups
size, both of them are for MACsec packets:
The first group is for MACsec packets which contains SCI field in the
SecTAG header.
The second group is for MACsec packets which doesn't contain SCI,
where need to match on the source MAC address (only if the SCI
is built from default MACsec port).
Destination MAC address, ethertype and some of SecTAG fields
are also matched for both groups.
In case of match, invoke decrypt action on the packet.
For each MACsec Rx offloaded SA two rules are created: one with SCI
and one without SCI.
The second FT (check table) has two fixed rules:
One rule is for verifying that the previous offload actions were
finished successfully.
In this case, need to decap the SecTAG header and forward the packet
for further processing.
Another default rule for dropping packets that failed in the previous
decrypt actions.
The MACsec FTs are created on demand when the first MACsec rule is
added and destroyed when the last MACsec rule is deleted.

MACsec driver marks Tx packets for device offload using a dedicated
skb_metadata_dst which holds a 64 bits SCI number.
A previously set rule will match on this number so the correct SA is used
for the MACsec operation.
As device driver can only provide 32 bits of metadata to flow tables,
need to used a mapping from 64 bit to 32 bits marker or id,
which is can be achieved by provide a 32 bit unique flow id in the
control path, and used a hash table to map 64 bit to the unique id in the
datapath.

Tx flow steering consists of two flow tables (FTs).
The first FT (crypto table) has two fixed rules:
One default miss rule so non MACsec offloaded packets bypass the MACSec
tables, another rule to make sure that MACsec key exchange (MKE) traffic
passes unencrypted as expected (matched of ethertype).
On each new MACsec offload flow, a new MACsec rule is added.
This rule is matched on metadata_reg_a (which contains the id of the
flow) and invokes the MACsec offload action on match.
The second FT (check table) has two fixed rules:
One rule for verifying that the previous offload actions were
finished successfully and packet need to be transmitted.
Another default rule for dropping packets that were failed in the
offload actions.
The MACsec FTs should be created on demand when the first MACsec rule is

be forward only to this device and not neccessarly to the desired one.

In the current MACsec offload implementation, MACsec interfaces shares
the same MAC address by default.
Therefore, HW can't distinguish from which MACsec interface the traffic
originated from.
MACsec stack will use skb_metadata_dst to store the SCI value, which is
unique per Macsec interface, skb_metadat_dst will be used by the
offloading device driver to associate the SKB with the corresponding
offloaded interface (SCI).

Add initial BYTE_ORDER read to sync the 32-bit accesses over the 16-bit
mdio bus to improve driver robustness.
The lan9303 expects two mdio read transactions back-to-back to read a
32-bit register. The first read transaction causes the other half of the
32-bit register to get latched. The subsequent read returns the latched
second half of the 32-bit read. The BYTE_ORDER register is an exception to
this rule. As it is a constant value, there is no need to latch the second
half. We read this register first in case there were reads during the boot
loader process that might have occurred prior to this driver taking over
ownership of accessing this device.
This patch has been tested on the SAMA5D3-EDS with a LAN9303 RMII daughter
card.

During stress tests with adding VF to namespace and changing vf's

Sometimes when IAVF_FLAG_AQ_DISABLE_QUEUES from iavf_close was sent
to PF after reset and before IAVF_AQ_GET_CONFIG was sent then PF
returns error IAVF_NOT_SUPPORTED to disable queues request and
following requests. There is need to get_config before other
aq_required will be send but iavf_close clears all flags, if
get_config was not sent before iavf_close, then it will not be send
at all.
In case when IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS was sent before
IAVF_FLAG_AQ_DISABLE_QUEUES then there was rtnl_lock deadlock
between iavf_close and iavf_adminq_task until iavf_close timeouts
and disable queues was sent after iavf_close ends.
There was also a problem with sending delete/add filters.
Sometimes when filters was not yet added to PF and in
iavf_close all filters was set to remove there might be a try
to remove nonexistent filters on PF.
Add aq_required_tmp to save aq_required flags and send them after
disable_queues will be handled. Clear flags given to iavf_down
different than IAVF_FLAG_AQ_GET_CONFIG as this flag is necessary
to sent other aq_required. Remove some flags that we don't
want to send as we are in iavf_close and we want to disable
interface. Remove filters which was not yet sent and send del
filters flags only when there are filters to remove.

.../ftmac100.c:208:23: warning: incorrect type in assignment (different base types)
.../ftmac100.c:208:23: expected unsigned int rxdes0
.../ftmac100.c:208:23: got restricted __le32 [usertype]
.../ftmac100.c:249:23: warning: invalid assignment: &=
.../ftmac100.c:249:23: left side has type unsigned int
.../ftmac100.c:249:23: right side has type restricted __le32
.../ftmac100.c:527:16: warning: cast to restricted __le32
Change type of some fields from 'unsigned int' to '__le32' to fix it.

We're not in a hot path and don't want to miss this message,
therefore remove the net_ratelimit() check.

Add 1000BASE-KX interface mode. This 1G backplane ethernet as described in
clause 70. Clause 73 autonegotiation is mandatory, and only full duplex
operation is supported.
Although at the PMA level this interface mode is identical to
1000BASE-X, it uses a different form of in-band autonegation. This
justifies a separate interface mode, since the interface mode (along
with the MLO_AN_* autonegotiation mode) sets the type of autonegotiation
which will be used on a link. This results in more than just electrical
differences between the link modes.
With regard to 1000BASE-X, 1000BASE-KX holds a similar position to
SGMII: same signaling, but different autonegotiation. PCS drivers
(which typically handle in-band autonegotiation) may only support
1000BASE-X, and not 1000BASE-KX. Similarly, the phy mode is used to
configure serdes phys with phy_set_mode_ext. Due to the different
electrical standards (SFI or XFI vs Clause 70), they will likely want to
use different configuration. Adding a phy interface mode for
1000BASE-KX helps simplify configuration in these areas.

Instead of setting the queue depth once during probe, adjust it on the
fly whenever we configure the link. This is a bit unusal, since usually
the DPAA driver calls into the FMAN driver, but here we do the opposite.
We need to add a netdev to struct mac_device for this, but it will soon
live in the phylink config.
I haven't tested this extensively, but it doesn't seem to break
anything. We could possibly optimize this a bit by keeping track of the
last rate, but for now we just update every time. 10GEC probably doesn't
need to call into this at all, but I've added it for consistency.

This adds a function to update a CGR with new parameters. qman_create_cgr
can almost be used for this (with flags=0), but it's not suitable because
it also registers the callback function. The _safe variant was modeled off
of qman_cgr_delete_safe. However, we handle multiple arguments and a return
value.
