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: 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.

sfc: determine representee m-port for EF100 representors

2022-07-22T11:50:06Z

An MAE port, or m-port, is a port (source/destination for traffic) on the Match-Action Engine (the internal switch on EF100). Representors will use their representee's m-port for two purposes: as a destination override on TX from the representor, and as a source match in 'default rules' to steer representee traffic (when not matched by e.g. a TC flower rule) to representor RX via the parent PF's receive queue.

sfc: Add a basic Siena module

2022-05-10T22:38:15Z

Make the (un)load message more specific to differentiate it from the sfc.ko messages. Signed-off-by: Martin Habets Signed-off-by: Jakub Kicinski

sfc: Disable Siena support

2022-05-04T10:18:08Z

Disable the build of Siena code until later in this patch series. Prevent sfc.ko from binding to Siena NICs. efx_init_sriov/efx_fini_sriov is only used for Siena. Remove calls to those. Signed-off-by: Martin Habets Signed-off-by: David S. Miller

sfc: add EF100 VF support via a write to sriov_numvfs

2022-04-30T01:43:01Z

This patch extends the EF100 PF driver by adding .sriov_configure() which would allow users to enable and disable virtual functions using the sriov sysfs.

sfc: skeleton EF100 PF driver

2020-07-27T19:26:55Z

No TX or RX path, no MCDI, not even an ifup/down handler. Besides stubs, the bulk of the patch deals with reading the Xilinx extended PCIe capability, which tells us where to find our BAR. Though in the same module, EF100 has its own struct pci_driver, which is named sfc_ef100. A small number of additional nic_type methods are added; those in the TX (tx_enqueue) and RX (rx_packet) paths are called through indirect call wrappers to minimise the performance impact.
