sfc: extend NVRAM MCDI handlers

2025-02-12T01:12:17Z

Support variable write-alignment, and background updates. The latter allows other MCDI to continue while the device is processing an MC_CMD_NVRAM_UPDATE_FINISH, since this can take a long time owing to e.g. cryptographic signature verification. Expose these handlers in mcdi.h, and build them even when CONFIG_SFC_MTD=n, so they can be used for devlink flash in a subsequent patch.

sfc: Remove unused mcdi functions

2024-11-06T01:35:11Z

efx_mcdi_flush_rxqs(), efx_mcdi_rpc_async_quiet(), efx_mcdi_rpc_finish_quiet(), and efx_mcdi_wol_filter_get_magic() are unused. I think these are fall out from the split into Siena that happened in commit 4d49e5cd4b09 ("sfc/siena: Rename functions in mcdi headers to avoid conflicts with sfc") and commit d48523cb88e0 ("sfc: Copy shared files needed for Siena (part 2)") Remove them.

sfc: offload left-hand side rules for conntrack

2023-08-09T10:14:38Z

Handle the (comparatively) simple case of a -trk rule on an efx netdev (i.e. not a tunnel decap rule) with ct and goto chain actions. Reviewed-by: Pieter Jansen van Vuuren Reviewed-by: Simon Horman Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: conntrack state matches in TC rules

2023-08-09T10:14:38Z

Parse ct_state trk/est, mark and zone out of flower keys, and plumb them through to the hardware, performing some minor translations. Nothing can actually hit them yet as we're not offloading any DO_CT actions. Reviewed-by: Pieter Jansen van Vuuren Reviewed-by: Simon Horman Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: add MAE table machinery for conntrack table

2023-08-09T10:14:37Z

Access to the connection tracking table in EF100 hardware is through a "generic" table mechanism, whereby a firmware call at probe time gives the driver a description of the field widths and offsets, so that the driver can then construct key and response bitstrings at runtime. Probe the NIC for this information and populate the needed metadata into a new meta_ct field of struct efx_tc_state.
