44ece4e1a3 ice: allow toggling loopback mode via ndo_set_features callback
Add support for NETIF_F_LOOPBACK. This feature can be set via:
$ ethtool -K eth0 loopback <on|off>

Feature can be useful for local data path tests.

c67672fa26 ice: compress branches in ice_set_features()
Instead of rather verbose comparison of current netdev->features bits vs
the incoming ones from user, let us compress them by a helper features
set that will be the result of netdev->features XOR features. This way,
current, extensive branches:

	if (features & NETIF_F_BIT && !(netdev->features & NETIF_F_BIT))
		set_feature(true);
	else if (!(features & NETIF_F_BIT) && netdev->features & NETIF_F_BIT)
		set_feature(false);

can become:

	netdev_features_t changed = netdev->features ^ features;

	if (changed & NETIF_F_BIT)
		set_feature(!!(features & NETIF_F_BIT));

This is nothing new as currently several other drivers use this
approach, which I find much more convenient.

a419526de6 ice: Fix promiscuous mode not turning off
When trust is turned off for the VF, the expectation is that promiscuous
and allmulticast filters are removed. Currently default VSI filter is not
getting cleared in this flow.

Example:

ip link set enp236s0f0 vf 0 trust on
ip link set enp236s0f0v0 promisc on
ip link set enp236s0f0 vf 0 trust off
/* promiscuous mode is still enabled on VF0 */

Remove switch filters for both cases.
This commit fixes above behavior by removing default VSI filters and
allmulticast filters when vf-true-promisc-support is OFF.

d7393425e7 ice: Introduce enabling promiscuous mode on multiple VF's
In current implementation default VSI switch filter is only able to
forward traffic to a single VSI. This limits promiscuous mode with
private flag 'vf-true-promisc-support' to a single VF. Enabling it on
the second VF won't work. Also allmulticast support doesn't seem to be
properly implemented when vf-true-promisc-support is true.

Use standard ice_add_rule_internal() function that already implements
forwarding to multiple VSI's instead of constructing AQ call manually.

Add switch filter for allmulticast mode when vf-true-promisc-support is
enabled. The same filter is added regardless of the flag - it doesn't
matter for this case.

Remove unnecessary fields in switch structure. From now on book keeping
will be done by ice_add_rule_internal().

Refactor unnecessarily passed function arguments.

To test:
1) Create 2 VM's, and two VF's. Attach VF's to VM's.
2) Enable promiscuous mode on both of them and check if
   traffic is seen on both of them.

Tony Nguyen says:

====================
ice: PPPoE offload support

Marcin Szycik says:

Add support for dissecting PPPoE and PPP-specific fields in flow dissector:
PPPoE session id and PPP protocol type. Add support for those fields in
tc-flower and support offloading PPPoE. Finally, add support for hardware
offload of PPPoE packets in switchdev mode in ice driver.

Example filter:
tc filter add dev $PF1 ingress protocol ppp_ses prio 1 flower pppoe_sid \
    1234 ppp_proto ip skip_sw action mirred egress redirect dev $VF1_PR

Changes in iproute2 are required to use the new fields (will be submitted
soon).

ICE COMMS DDP package is required to create a filter in ice.

cc1049ccee net: dsa: mv88e6xxx: fix speed setting for CPU/DSA ports
Commit 3c783b83bd ("net: dsa: mv88e6xxx: get rid of SPEED_MAX setting")
stopped relying on SPEED_MAX constant and hardcoded speed settings
for the switch ports and rely on phylink configuration.

It turned out, however, that when the relevant code is called,
the mac_capabilites of CPU/DSA port remain unset.
mv88e6xxx_setup_port() is called via mv88e6xxx_setup() in
dsa_tree_setup_switches(), which precedes setting the caps in
phylink_get_caps down in the chain of dsa_tree_setup_ports().

As a result the mac_capabilites are 0 and the default speed for CPU/DSA
port is 10M at the start. To fix that, execute mv88e6xxx_get_caps()
and obtain the capabilities driectly.

aa5b8b73d4 net: dsa: microchip: add common ksz port xmii speed selection function
This patch adds the function for configuring the 100/10Mbps speed
selection for the ksz switches. KSZ8795 switch uses Global control 4
register 0x06 bit 4 for choosing 100/10Mpbs. Other switches uses xMII
control 1 0xN300 for it.
For KSZ8795, if the bit is set then 10Mbps is chosen and if bit is
clear then 100Mbps chosen. For all other switches it is other way
around, if the bit is set then 100Mbps is chosen.
So, this patch add the generic function for ksz switch to select the
100/10Mbps speed selection. While configuring, first it disables the
gigabit functionality and then configure the respective speed.

This patch add helper function for setting and getting the gigabit
enable for the ksz series switch. KSZ8795 switch has different register
address compared to all other ksz switches. KSZ8795 series uses the Port
5 Interface control 6 Bit 6 for configuring the 1Gbps or 100/10Mbps
speed selection. All other switches uses the xMII control 1 0xN301
register Bit6 for gigabit.
Further, for KSZ8795 & KSZ9893 switches if bit 1 then 1Gbps is chosen
and if bit 0 then 100/10Mbps is chosen. It is other way around for
other switches bit 0 is for 1Gbps. So, this patch implements the common
function for configuring the gigabit set and get capability.

====================
40GbE Intel Wired LAN Driver Updates 2022-07-22

This series contains updates to i40e and iavf drivers.

Przemyslaw adds a helper function for determining whether TC MQPRIO is
enabled for i40e.

Avinash utilizes the driver's bookkeeping of filters to check for
duplicate filter before sending the request to the PF for iavf.

2830e31477 net: ethernet: mtk-ppe: fix traffic offload with bridged wlan
A typical flow offload scenario for OpenWrt users is routed traffic
received by the wan interface that is redirected to a wlan device
belonging to the lan bridge. Current implementation fails to
fill wdma offload info in mtk_flow_get_wdma_info() since odev device is
the local bridge. Fix the issue running dev_fill_forward_path routine in
mtk_flow_get_wdma_info in order to identify the wlan device.

The function mlxsw_sp_ptp_phc_adjfreq() configures MTUTC register to adjust

This configuration will be same for Spectrum-2. In preparation for

Later, it will be used for Spectrum-2 also.

Spectrum-1 and Spectrum-2 differ in their time stamping capabilities.
The former can be configured to time stamp only a subset of received PTP
events (e.g., only Sync), whereas the latter will time stamp all PTP
events or none.

In preparation for Spectrum-2 PTP support, rename the function that
parses the hardware time stamping configuration upon %SIOCSHWTSTAMP to
be Spectrum-1 specific.

Currently, there is one shared structure that holds the required

be specific for Spectrum-1 and align the existing code. Add a common
structure which includes the structures which will be used also for
Spectrum-2. This structure will be returned from clock_init() operation,
as the definition is shared between all ASICs' operations.

9468322963 mlxsw: pci: Simplify FRC clock reading
Currently, the reading of FRC values (high and low) is done using macro
which calls to a function. In addition, to calculate the offset of FRC,
a simple macro is used. This code can be simplified by adding an helper
function and calculating the offset explicitly instead of using an
additional macro for that.

Add the helper function and convert the existing code. This helper will be
used later to read UTC clock.

22d950b79e mlxsw: spectrum_ptp: Initialize the clock to zero as part of initialization
As lately recommended in the mailing list[1], set the clock to zero time as
part of initialization.

The idea is that when the clock reads 'Jan 1, 1970', then it is clearly
wrong and user will not mistakenly think that the clock is set correctly.
If as part of initialization, the driver sets the clock, user might see
correct date and time (maybe with a small shift) and assume that there
is no need to sync the clock.

Fix the existing code of Spectrum-1 to set the 'timecounter' to zero.

448e9cb363 mlxsw: resources: Add resource identifier for maximum number of FIDs
Add a resource identifier for maximum number of FIDs so that it could be
later used to query the information from firmware.

In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are
sent as control packets is not updated at egress port. To overcome this
limitation, some packets will be sent as data packets. The header should
include FID, which is supposed to be 'Max FID + port - 1'. As preparation,
add the required resource, to be able to query the value from firmware
later.
