netdev_features: convert NETIF_F_LLTX to dev->lltx

2024-09-03T09:36:43Z

NETIF_F_LLTX can't be changed via Ethtool and is not a feature, rather an attribute, very similar to IFF_NO_QUEUE (and hot). Free one netdev_features_t bit and make it a "hot" private flag. Signed-off-by: Alexander Lobakin Signed-off-by: Paolo Abeni

sfc: add support for devlink port_function_hw_addr_get in ef100

2023-02-16T11:03:13Z

Using the builtin client handle id infrastructure, add support for obtaining the mac address linked to mports in ef100. This implies to execute an MCDI command for getting the data from the firmware for each devlink port.

sfc: add devlink port support for ef100

2023-02-16T11:03:12Z

Using the data when enumerating mports, create devlink ports just before netdevs are registered and remove those devlink ports after netdev has been unregistered. Signed-off-by: Alejandro Lucero Reviewed-by: Jiri Pirko Acked-by: Martin Habets Signed-off-by: Paolo Abeni

sfc: add mport lookup based on driver's mport data

2023-02-16T11:03:12Z

Obtaining mport id is based on asking the firmware about it. This is still needed for mport initialization itself, but once the mport data is now kept by the driver, further mport id request can be satisfied internally without firmware interaction. Previous function is just modified in name making clear the firmware interaction. The new function uses the old name and looks for the data in the mport data structure.

sfc: enumerate mports in ef100

2023-02-16T11:03:12Z

MAE ports (mports) are the ports on the EF100 embedded switch such as networking PCIe functions, the physical port, and potentially others. Signed-off-by: Alejandro Lucero Acked-by: Martin Habets Signed-off-by: Paolo Abeni

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

sfc: add a hashtable for offloaded TC rules

2022-09-28T08:43:22Z

Nothing inserts into this table yet, but we have code to remove rules on FLOW_CLS_DESTROY or at driver teardown time, in both cases also attempting to remove the corresponding hardware rules. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: bind blocks for TC offload on EF100

2022-09-28T08:43:22Z

Bind direct blocks for the MAE-admin PF and each VF representor. Currently these connect to a stub efx_tc_flower() that only returns -EOPNOTSUPP; subsequent patches will implement flower offloads to the Match-Action Engine. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: implement ethtool get/set RX ring size for EF100 reps

2022-07-30T04:22:07Z

It's not truly a ring, but the maximum length of the list of queued RX SKBs is analogous to an RX ring size, so use that API to configure it. Signed-off-by: Edward Cree Signed-off-by: Jakub Kicinski

sfc: insert default MAE rules to connect VFs to representors

2022-07-30T04:22:06Z

Default rules are low-priority switching rules which the hardware uses in the absence of higher-priority rules. Each representor requires a corresponding rule matching traffic from its representee VF and delivering to the PF (where a check on INGRESS_MPORT in __ef100_rx_packet() will direct it to the representor). No rule is required in the reverse direction, because representor TX uses a TX override descriptor to bypass the MAE and deliver directly to the VF. Since inserting any rule into the MAE disables the firmware's own default rules, also insert a pair of rules to connect the PF to the physical network port and vice-versa.
