sfc: neighbour lookup for TC encap action offload For each neighbour we're interested in, create a struct efx_neigh_binder object which has a list of all the encap_actions using it. When we receive a neighbouring update (through the netevent notifier), find the corresponding efx_neigh_binder and update all its users. Since the actual generation of encap headers is still only a stub, the resulting rules still get left on fallback actions.

sfc: obtain device mac address based on firmware handle for ef100 Getting device mac address is currently based on a specific MCDI command only available for the PF. This patch changes the MCDI command to a generic one for PFs and VFs based on a client handle. This allows both PFs and VFs to ask for their mac address during initialization using the CLIENT_HANDLE_SELF. Moreover, the patch allows other client handles which will be used by the PF to ask for mac addresses linked to VFs. This is necessary for suporting the port_function_hw_addr_get devlink function in further patches.

sfc: insert default MAE rules to connect VFs to representors 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: skeleton EF100 PF driver 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.
