matchall rules can be added only to chain 0 and their priorities have
limitations:
- new matchall ingress rule's priority must be higher (lower value)
than any existing flower rule;
- new matchall egress rule's priority must be lower (higher value)
than any existing flower rule.
The opposite works for flower rule adding:
- new flower ingress rule's priority must be lower (higher value)
than any existing matchall rule;
- new flower egress rule's priority must be higher (lower value)
than any existing matchall rule.
This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.
To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.

This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and
TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers

This also extracts matchall rules management out of SPAN API since SPAN

When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll

This is incorrect for two reasons:
* the function terminates without enabling interrupts or scheduling NAPI,
* the error code (-ENOMEM) is returned instead of the number of received
packets.
After the first memory allocation failure occurs, packet reception is
locked due to disabled interrupts from DMA..

This is a follow-up to the discussion in [0]. It seems to me that
at least the IP version used on Amlogic SoC's sometimes has a problem
if register MAC_CTRL_REG is written whilst the chip is still processing
a previous write. But that's just a guess.
Adding a delay between two writes to this register helps, but we can
also simply omit the offending second write. This patch uses the second
approach and is based on a suggestion from Qi Duan.
Benefit of this approach is that we can save few register writes, also
on not affected chip versions.

There is a case found in heavy testing where a link flap happens just
before a firmware Recovery event and the driver gets stuck in the
BROKEN state. This comes from the driver getting interrupted by a FW
generation change when coming back up from the link flap, and the call
to ionic_start_queues() in ionic_link_status_check() fails. This can be
addressed by having the fw_up code clear the BROKEN bit if seen, rather
than waiting for a user to manually force the interface down and then
back up.

The ixgbe_ptp_start_cyclecounter is intended to be called whenever the
cyclecounter parameters need to be changed.
Since commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x
devices"), this function has cleared the SYSTIME registers and reset the
TSAUXC DISABLE_SYSTIME bit.
While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear
them during ixgbe_ptp_start_cyclecounter. This function may be called
during both reset and link status change. When link changes, the SYSTIME
counter is still operating normally, but the cyclecounter should be updated
to account for the possibly changed parameters.
Clearing SYSTIME when link changes causes the timecounter to jump because
the cycle counter now reads zero.
Extract the SYSTIME initialization out to a new function and call this
during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids
an unnecessary reset of the current time.
This also restores the original SYSTIME clearing that occurred during
ixgbe_ptp_reset before the commit above.

Add support for SF tunnel offload
Mlx5 driver only supports VF tunnel offload.
To add support for SF tunnel offload the driver needs to:
1. Add send-to-vport metadata matching rules like done for VFs.
2. Set an indirect table for SF vport, same as VF vport.
info smaller sub functions for better maintainability.
rules from esw init phase to representor load phase.
SFs could be created after esw initialized and thus the send-to-vport
meta rules would not be created for those SFs.
By moving the creation of the rules to representor load phase
we ensure creating the rules also for SFs created later.

Make TC's private, let mlx5e_flow_steering struct be dynamically allocated,

instead of publicly exposing it.
Introduce flow steering debug macros to provide an elegant finish to the
decoupled flow steering API, where errors related to flow steering shall

mlx5-updates-2022-08-22
Roi Dayan Says:
===============
Add support for SF tunnel offload
Mlx5 driver only supports VF tunnel offload.
To add support for SF tunnel offload the driver needs to:
1. Add send-to-vport metadata matching rules like done for VFs.
2. Set an indirect table for SF vport, same as VF vport.
info smaller sub functions for better maintainability.
rules from esw init phase to representor load phase.
SFs could be created after esw initialized and thus the send-to-vport
meta rules would not be created for those SFs.
By moving the creation of the rules to representor load phase
we ensure creating the rules also for SFs created later.

================
Make flow steering API loosely coupled from mlx5e_priv, in a manner to
introduce more readable and maintainable modules.
Make TC's private, let mlx5e_flow_steering struct be dynamically allocated,
and introduce its API to maintain the code via setters and getters
instead of publicly exposing it.
Introduce flow steering debug macros to provide an elegant finish to the
decoupled flow steering API, where errors related to flow steering shall
be reported via them.
All flow steering related files will drop any coupling to mlx5e_priv,
instead they will get the relevant members as input. Among these,
fs_tt_redirect, fs_tc, and arfs.

Issue found during code review. This bug has no impact as long as the
ks8851_net structure is the first element of the ks8851_net_spi structure.
As long as the offset to the ks8851_net struct is zero, the container_of()
macro is subtracting 0 and therefore no damage done. But if the
ks8851_net_spi struct is ever modified such that the ks8851_net struct
within it is no longer the first element of the struct, then the bug would
manifest itself and cause problems.
struct ks8851_net is contained within ks8851_net_spi.
ks is contained within kss.
kss is the priv_data of the netdev structure.

Both <port> br_port_locked and <lag> interfaces's flag
offloading is supported. No new ABI is being added,
rather existing (port_param_set) API call gets extended.

V2:
add missing receipents (linux-kernel, netdev)
Signed-off-by: David S. Miller <davem@davemloft.net>
On link state change, the controller gets reset,
causing PPS to drop out and the PHC to lose its
time and calibration. So we restart it if needed,
restoring calibration and time registers.
Changes since v2:
* Add `fec_ptp_save_state()`/`fec_ptp_restore_state()`
* Use `ktime_get_real_ns()`
* Use `BIT()` macro
Changes since v1:
* More ECR #define's
* Stop PPS in `fec_ptp_stop()`

In TI's J7200 SoC CPSW5G ports, each of the 4 ports can be configured
as a QSGMII main or QSGMII-SUB port. This configuration is performed
by phy-gmii-sel driver on invoking the phy_set_mode_ext() function.
It is necessary for the QSGMII main port to be configured before any of
the QSGMII-SUB interfaces are brought up. Currently, the QSGMII-SUB
interfaces come up before the QSGMII main port is configured.
Fix this by moving the call to phy_set_mode_ext() from
am65_cpsw_nuss_ndo_slave_open() to am65_cpsw_nuss_init_slave_ports(),
thereby ensuring that the QSGMII main port is configured before any of
the QSGMII-SUB ports are brought up.

this small series is supposed to fix the issues around AF_XDP usage with
reduced queue count on interface. Due to the XDP rings setup, some

Implement line card operation callbacks got_active() / got_inactive().
The purpose of these callback to create / remove line card ports after
line card is getting active / inactive.
Implement line ports_remove_selected() callback to support line card
un-provisioning flow through 'devlink'.
Add line card operation registration and de-registration APIs.
Add module offset for line card. Offset for main board iz zero.
For line card in slot #n offset is calculated as (#n - 1) multiplied by
maximum modules number.
