The mvpp2_phylink_validate() sets all modes that are supported by a
given PPv2 port. An mistake made the 10000baseT_Full mode being
advertised in some cases when a port wasn't configured to perform at
10G. This patch fixes this.

The mvpp2_phylink_validate() function sets all modes that are
supported by a given PPv2 port. A recent change made all ports to
advertise they support 10G modes in certain cases. This is not true,
as only the port #0 can do so. This patch fixes it.

Recent changes in the mvneta driver reworked allocation
and handling of the ingress buffers to use entire pages.
Apart from that in SW BM scenario the HW must be informed
via PRXDQS about the biggest possible incoming buffer
that can be propagated by RX descriptors.
The BufferSize field was filled according to the MTU-dependent
pkt_size value. Later change to PAGE_SIZE broke RX operation
when usin 64K pages, as the field is simply too small.
This patch conditionally limits the value passed to the BufferSize
of the PRXDQS register, depending on the PAGE_SIZE used.
On the occasion remove now unused frag_size field of the mvneta_port
structure.

The mvpp2_phylink_validate() relies on the interface field of
phylink_link_state to determine valid link modes. However, when called
from phylink_sfp_module_insert() this field in not initialized. The
default switch case then excludes 10G link modes. This allows 10G SFP
modules that are detected correctly to be configured at max rate of
2.5G.
Catch the uninitialized PHY mode case, and allow 10G rates.

Using 2.5G speed relies on the SerDes lanes being configured
accordingly. The lanes have to be reconfigured to switch between
1G and 2.5G, and for now only the bootloader does this configuration.
In the case we add a Comphy driver to handle switching the lanes
dynamically, it's better for now to stick with supporting only 1G and
add advertisement for 2.5G once we really are capable of handling both
speeds without problem.
Since the interface mode is initialy taken from the DT, we want to make
sure that adding comphy support won't break boards that don't update
their dtb.

The mvpp2 driver has the curious behaviour of passing a stack variable
to irq_set_affinity_hint(), which results in the kernel exploding
the first time anyone accesses this information. News flash: userspace
does, and irqbalance will happily take the machine down. Great stuff.
An easy fix is to track the mask within the queue_vector structure,
and to make sure it has the same lifetime as the interrupt itself.

By default NIXLF is set in UCAST mode. This patch adds a new
mailbox message which when sent by a RVU PF changes this default
mode. When promiscuous mode is needed, the reserved promisc entry
for each of RVU PF is setup to match against ingress channel number
only, so that all pkts on that channel are accepted and forwarded
to the mode change requesting PF_FUNC's NIXLF.
PROMISC and ALLMULTI modes are supported only for PFs, for VFs only
UCAST mode is supported.

Configure NIX RX flowkey algorithm configuration to support
RSS (receive side scaling). Currently support for only L3/L4
2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added.
HW supports upto 32 different flowkey algorithms which SW
can define, this patch defines 9. NPC RX ACTION has to point
to one of these flowkey indices for RSS to work.
The configuration is dependent on NPC parse result's layer
info. So if NPC KPU profile changes suchthat LID/LTYPE values
of above said protocols change then this configuration will
most likely be effected.

This patch adds some minimal configuration for NPC MCAM and
LDATA extraction which is sufficient enough to install
ucast/bcast/promiscuous forwarding rules. Below is the
config done
- LDATA extraction config to extract DMAC from pkt
to offset 64bit in MCAM search key.
- Set MCAM lookup keysize to 224bits
- Set MCAM TX miss action to UCAST_DEFAULT
- Set MCAM RX miss action to DROP
Also inorder to have guaranteed space in MCAM to install
ucast forwarding rule for each of RVU PF/VF, reserved
one MCAM entry for each of NIXLF for ucast rule. And two
entries for each of RVU PF. One for bcast pkt replication
and other for promiscuous mode which allows all pkts
received on a HW CGX/LBK channel.

This patch adds support for a PF/VF driver to configure
NIX transmit scheduler queues via mbox. Since PF/VF doesn't
know the absolute HW index of the NIXLF attached to it, AF
traps the register config and overwrites with the correct
NIXLF index.
HW supports shaping, colouring and policing of packets with
these multilevel traffic scheduler queues. Instead of
introducing different mbox message formats for different
configurations and making both AF & PF/VF driver implementation
cumbersome, access to the scheduler queue's CSRs is provided
via mbox. AF checks whether the sender PF/VF has the
corresponding queue allocated or not and dumps the config
to HW. With a single mbox msg 20 registers can be configured.

Added support for a PF/VF to allocate or free NIX transmit
scheduler queues via mbox. For setting up pkt transmission
priorities between queues, the scheduler queues have to be

Upon receiving NIX_TXSCH_FREE mbox msg all scheduler queues
allocated to sending PFFUNC (PF/VF) will be freed. Selective

- Added mbox msgs so that PFs can register/unregister for link events.
- Link notifications are sent to PF under two scenarioss.
1. When a asynchronous link change notification is received from
firmware with notification flag turned on for that PF.
2. Upon notification turn on request, the current link status is

Instead of looping on a integer timeout, use time_before(jiffies),
so that maximum poll time is capped.

The newly added driver causes a warning about a function that is
not used anywhere:
drivers/net/ethernet/marvell/octeontx2/af/cgx.c:320:12: error: 'cgx_fwi_link_change' defined but not used [-Werror=unused-function]
Remove it for now, until a user gets added. If we want to use this
function from another module, we also need a declaration in a header
file, which is currently missing, so it would have to change anyway.
