Truesize is now passed directly to i40e_rx_buffer_flip() instead of size
so that it does not need to recalculate truesize from size using
i40e_rx_frame_truesize() before adjusting page offset.
With these change the function can now be used during skb building and
adding frags. In later patches it will also be easier for adjusting
page offsets for multi-buffers.

Page count of rx_buffer needs to be stored prior to XDP call to prevent
page recycling in case that buffer would be freed within xdp redirect
path. Instead of storing it on the stack, now it is stored in the
rx_buffer struct. This will help in processing multi-buffers as the page
counts of all rx_buffers (of the same packet) don't need to be stored on
stack.

Adding support for XDP multi-buffer entails adding information of all
the fragments of the packet in the xdp_buff. This approach implies that
underlying buffer has to provide tailroom for skb_shared_info.
In the legacy-rx mode, driver can only configure up to 2k sized Rx buffers
and with the current configuration of 2k sized Rx buffers there is no way
to do tailroom reservation for skb_shared_info. Hence size of Rx buffers
is now lowered to 2048 - sizeof(skb_shared_info). Also, driver can only
chain up to 5 Rx buffers and this means max MTU supported for legacy-rx
is now 8614 (5 * rx_buffer_len - ETH header with VLAN).

Introduce new helper function to calculate max frame size for validating
and setting of vsi frame size. This is used while configuring vsi,
changing the MTU and attaching an XDP program to the vsi.
This is in preparation of the legacy rx and multi-buffer changes to be
introduced in later patches.

Since the conversion of mtk_eth_soc to phylink's supported_interfaces
bitmap, these two modes have not been selectable. No one has raised
this as an issue. Checking the in-kernel DT files, none of them use
either of these modes with this hardware.
Daniel Golle concurs:
A quick grep through the device trees of the more than 650 ramips and
mediatek boards we support in OpenWrt has revealed that *none* of them
uses either reduced-MII or reverse-MII PHY modes. I could imaging that
some more specialized ramips boards may use the RMII 100M PHY mode to
connect with exotic PHYs for industrial or automotive applications
(think: for 100BASE-T1 PHY connected via RMII). I have never seen or
touched such boards, but there are hints that they do exist.
For reverse-MII there are cases in which the Ralink SoC (Rt305x, for
example) is used in iNIC mode, ie. connected as a PHY to another SoC,
and running only a minimal firmware rather than running Linux. Due to
the lack of external DRAM for the Ralink SoC on this kind of boards,
the Ralink SoC there will anyway never be able to boot Linux.
I've seen this e.g. in multimedia devices like early WiFi-connected
not-yet-so-smart TVs.
Consequently, the conclusion is that no one uses these modes with this
hardware, so we might as well drop support for them.

If TRGMII mode is not permitted when using DDR2 mode, we should handle
that when setting up phylink's ->supported_interfaces so phylink knows

R-Car H3 ES1.* was only available to an internal development group and
needed a lot of quirks and workarounds. These become a maintenance
burden now, so our development group decided to remove upstream support
and disable booting for this SoC. Public users only have ES2 onwards.

This adds support for using the "template add" and "template destroy"
functionality to change the port keyset configuration.
If the VCAP lookup already contains rules, the port keyset is left
unchanged, as a change would make these rules unusable.
When the template is destroyed the port keyset configuration is restored.
The filters using the template chain will automatically be deleted by the
TC framework.

With this its is now possible for clients (like TC) to change the port
keyset configuration in the Sparx5 VCAPs.
This is typically done per traffic class which is guided with the L3
protocol information.
Before the change the current keyset configuration is collected in a list
that is handed back to the client.

Fix deletion of existing DSCP mappings in the APP table.
Adding and deleting DSCP entries are replicated per-port, since the
mapping table is global for all ports in the chip. Whenever a mapping
for a DSCP value already exists, the old mapping is deleted first.
However, it is only deleted for the specified port. Fix this by calling
sparx5_dcb_ieee_delapp() instead of dcb_ieee_delapp() as it ought to be.
Reproduce:
// Map and remap DSCP value 63
$ dcb app add dev eth0 dscp-prio 63:1
$ dcb app add dev eth0 dscp-prio 63:2
$ dcb app show dev eth0 dscp-prio
dscp-prio 63:2
$ dcb app show dev eth1 dscp-prio

detection
NDC caches contexts of frequently used queue's (Rx and Tx queues)
contexts. Due to a HW errata when NDC detects fault/poision while
accessing contexts it could go into an illegal state where a cache
line could get locked forever. To makesure all cache lines in NDC
are available for optimum performance upon fault/lockerror/posion
errors scan through all cache lines in NDC and clear the lock bit.

Zero-length arrays as fake flexible arrays are deprecated and we are
moving towards adopting C99 flexible-array members instead.
Transform zero-length array into flexible-array member in struct
mlx4_en_rx_desc.
Address the following warnings found with GCC-13 and
-fstrict-flex-arrays=3 enabled:
drivers/net/ethernet/mellanox/mlx4/en_rx.c:88:30: warning: array subscript i is outside array bounds of ‘struct mlx4_wqe_data_seg[0]’ [-Warray-bounds=]
drivers/net/ethernet/mellanox/mlx4/en_rx.c:149:30: warning: array subscript 0 is outside array bounds of ‘struct mlx4_wqe_data_seg[0]’ [-Warray-bounds=]

drivers/net/ethernet/mellanox/mlx4/en_rx.c:119:30: warning: array subscript i is outside array bounds of ‘struct mlx4_wqe_data_seg[0]’ [-Warray-bounds=]
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].

Now that ASPM is disabled during NAPI poll, we can remove all ASPM
restrictions. This allows for higher power savings if the network
isn't fully loaded.

Several chip versions have problems with ASPM, what may result in
rx_missed errors or tx timeouts. The root cause isn't known but
experience shows that disabling ASPM during NAPI poll can avoid
these problems.
