This series enables DPDK to use the sfc driver on a Medford4 VF alongside the PF.
The first patch wires EVB switch operations into the Medford4 libefx implementation, allowing the PF to manage VFs. Starting with MCFW 1.4.0.8, VFs may use the netport MCDI for basic port configuration, though several operations remain restricted. The remaining four patches address each restriction: dummy fixed port properties, suppressed event subscription, denied FCS and flow control, and ENOTSUP for periodic MAC stats DMA. This series depends on the VADAPTER statistics series. v4: - addressed https://mails.dpdk.org/archives/dev/2026-August/343468.html -- patch 2/6: fixed VF PERM mask derivation; all speeds from the tech table are now used unconditionally, rather than the advertised abilities, which are empty when the PF operates in fixed-speed mode; output params of efx_np_get_fixed_port_props are now zeroed on the VF early-return path -- patch 3/6: noted the no-op for VFs in the call site comment of efx_np_set_event_mask -- patch 6/6: added SR-IOV VF limitations subsection to the Limitations section of sfc_efx.rst v3: - addressed https://mails.dpdk.org/archives/dev/2026-August/343075.html -- patch 6/6: dropped erroneous VADAPTER mention from the commit message; added SR-IOV VF to sfc_efx.rst v2: - note for the future AI reviews: apply this on top of the 'common/sfc_efx/base: add VADAPTER statistics for Medford4' series - addressed https://mails.dpdk.org/archives/dev/2026-August/343075.html -- fixed reporting of the factual link speed when running on VFs -- remaining notes do not seem to point at factual defects Ivan Malov (6): common/sfc_efx/base: let Medford4 PF manage VFs common/sfc_efx/base: indicate dummy netport properties on VF common/sfc_efx/base: skip netport event subscriptions on VFs common/sfc_efx/base: deny tuning FCS and flow control to VFs common/sfc_efx/base: deny periodic MAC stats delivery to VFs doc: announce VF support of AMD Solarflare X45xx family NICs doc/guides/nics/sfc_efx.rst | 23 ++++++ doc/guides/rel_notes/release_26_11.rst | 4 + drivers/common/sfc_efx/base/efx_evb.c | 6 ++ drivers/common/sfc_efx/base/efx_np.c | 107 ++++++++++++++++++++++--- 4 files changed, 127 insertions(+), 13 deletions(-) -- 2.47.3
