These are needed in order to implement the switchdev FDB callbacks.
Compared to the E/T generation, not only the ABI (bit offsets) is
different, but also the introduction of the HOSTCMD field which permits
O(1) TCAM search for an FDB entry. Make use of the newly introduce
OP_SEARCH to permit that. It will be used while adding and deleting an
FDB entry (to see whether it exists or not).

The DSA callbacks were written with the E/T (first generation) in mind,
which is quite different.
For P/Q/R/S completely new implementations need to be provided, which
are held as function pointers in the priv->info structure. We are
taking a slightly roundabout way for this (a function from
sja1105_main.c reads a structure defined in sja1105_spi.c that
points to a function defined in sja1105_main.c), but it is what it is.
The FDB dump callback works for both families, hence no function pointer
for that.

Only a single dynamic configuration table of the SJA1105 P/Q/R/S
supports this operation: the FDB.
To keep the existing structure in place (sja1105_dynamic_config_read and
sja1105_dynamic_config_write) and not introduce any new function, a
convention is made for sja1105_dynamic_config_read that a negative index
argument denotes a search for the entry provided as argument.

All RAS and MSI-X should be enabled just in the final stage of HNS3
initialization. It means that they should be enabled in
hclge_init_xxx_client_instance instead of hclge_ae_dev(). Especially
MSI-X, if it is enabled before opening vector0 IRQ, there are some
chances that a MSI-X error will cause failure on initialization of
NIC client instane. So this patch delays enabling of HW errors.
Otherwise, we also separate enabling of ROCE RAS from NIC, because
it's not reasonable to enable ROCE RAS if we even don't have a ROCE
driver.

Some SFP modules do not like reads longer than 16 bytes, so read the
EEPROM in chunks of 16 bytes at a time. This behaviour is not specified
in the SFP MSAs, which specifies:
"The serial interface uses the 2-wire serial CMOS E2PROM protocol
defined for the ATMEL AT24C01A/02/04 family of components."
and
"As long as the SFP+ receives an acknowledge, it shall serially clock
out sequential data words. The sequence is terminated when the host
responds with a NACK and a STOP instead of an acknowledge."
We must avoid breaking a read across a 16-bit quantity in the diagnostic
page, thankfully all 16-bit quantities in that page are naturally
aligned.

MT7629 inlcudes two sets of SGMIIs used for external switch or PHY, and embedded
switch (ESW) via GDM1, GePHY via GMAC2, so add several patches in the series to
make the code base common with the old SoCs.
The patch 1, 3 and 6, adds extension for SGMII to have the hardware configured
for 1G, 2.5G and AN to fit the capability of the target PHY. In patch 6 could be
an example showing how to use these configurations for underlying PHY speed to
match up the link speed of the target PHY.
The patch 4 is used for automatically configured the hardware path from GMACx to

This series provides some updates to mlx5 core and netdevice driver.
1) use __netdev_tx_sent_queue() to improve performance under GSO workload
2) Allow matching only enc_key_id/enc_dst_port for decapsulation action
3) Geneve support:
This patchset adds support for GENEVE tunnel encap/decap flows offload:
encapsulating layer 2 Ethernet frames within layer 4 UDP datagrams.
The driver supports 6081 destination UDP port number, which is the
default IANA-assigned port.
Encap:
ConnectX-5 inserts the header (w/ or w/o Geneve TLV options) that is
provided by the mlx5 driver to the outgoing packet.
Decap:
Geneve header is matched and the packet is decapsulated.
Notes about decap flows with Geneve TLV Options:
- Support offloading of 32-bit options data only
- At any given time, only one combination of class/type parameters
can be offloaded, but the same class/type combination can have
many different flows offloaded with different 32-bit option data
- Options with value of 0 can't be offloaded
Managing Geneve TLV options:
Matching (on receive) is done by ConnectX-5 flex parser.
Geneve TLV options are managed using General Object of type
“Geneve TLV Options”.
When the first flow with a certain class/type values is requested
to be offloaded, the driver creates a FW object with FW command
(Geneve TLV Options general object) and starts counting the number
of flows using this object.
During this time, any request with a different class/type values
will fail to be offloaded.
Once the refcount reaches 0, the driver destroys the TLV options
general object, and can now offload a flow with any class/type parameters.
Geneve TLV Options object is added to core device.
It is currently used to manage Geneve TLV options general
object allocation in FW and its reference counting only.
In the future it will also be used for managing geneve ports
by registering callbacks for ndo_udp_tunnel_add/del.
TC tunnel code refactoring:
As a preparation for Geneve code, the TC tunnel code in mlx5
was rearranged in a modular way, so that it would be easier
to add future tunnels:
- Defined tc tunnel object with the fields and callbacks that
any tunnel must implement.
- Define tc UDP tunnel object for UDP tunnels, such as VXLAN
- Move each tunnel code (GRE, VXLAN) to its own separate file
- Rewrite tc tunnel implementation in a general way – using
only the objects and their callbacks.
4) Termination tables:
Actions in tables set with the termination flag are guaranteed to terminate
the action list. Thus, potential looping functionality (e.g. haripin) can safely be
executed without potential loops.
