2023-06-16sfc: do not try to call tc functions when CONFIG_SFC_SRIOV=nEdward Cree
Functions efx_tc_netdev_event and efx_tc_netevent_event do not exist in that case as object files tc_bindings.o and tc_encap_actions.o are not built, so the calls to them from ef100_netdev_event and ef100_netevent_event cause link errors. Wrap the corresponding header files (tc_bindings.h, tc_encap_actions.h) with #if IS_ENABLED(CONFIG_SFC_SRIOV), and add an #else with static inline stubs for these two functions.

2023-06-10sfc: neighbour lookup for TC encap action offloadEdward Cree
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.

2022-09-28sfc: bind indirect blocks for TC offload on EF100Edward Cree
Bind indirect blocks for recognised tunnel netdevices. Currently these connect to a stub efx_tc_flower() that only returns -EOPNOTSUPP; subsequent patches will implement flower offloads to the Match-Action Engine.
