Patch 1 is a pure refactor (no functional change) that relocates the filter and VNIC related code into the appropriate files. Patch 7 drops the refcount usage from L2 filters, also with no functional change. The subsequent patches then add the ethtool commands for configuring ntuple flows and RSS contexts.

Explanation: bnge_toeplitz() is not used for aRFS. Patch-9: Comment regarding bnge_clear_usr_fltrs(). Explanation: Both bnge_clear_usr_fltrs() (only invoked while the interface is down) and bnge_grxclsrule() execute under the netdev instance lock, so they are serialized and never touch the filter list at the same time. Patch-10: Comment "Does this direct dereference of the MAC header need a linearization ...". Explanation: ndo_rx_flow_steer runs on the RX path after eth_type_trans(), which already accesses and pulls the Ethernet header. Comment Related to bnge_cfg_ntp_filters(). Explanation: bnge_cfg_ntp_filters() runs from bnge_sp_task(), which holds the netdev instance lock while executing. v1->v2: - Build fixes. - Addressed comments from Sashiko https://sashiko.dev/#/patchset/20260814011435.194631-1-vikas.gupta%40broadcom.com Vikas Gupta (10): bnge: restructure VNIC and filter code bnge: add NTUPLE/ARFS VNIC bnge: add helper functions for multi RSS contexts bnge: add RXFH ethtool support bnge: add ethtool support to manage RSS contexts bnge: remove refcount from L2 filter bnge: add NTUPLE filter infrastructure bnge: add NTUPLE filter support in ethtool bnge: add aRFS flow steering ndo support bnge: add cpu_rmap support for IRQ affinity drivers/net/ethernet/broadcom/bnge/Makefile | 4 +- drivers/net/ethernet/broadcom/bnge/bnge.h | 13 +- .../net/ethernet/broadcom/bnge/bnge_ethtool.c | 1126 +++++++++++++++++ .../net/ethernet/broadcom/bnge/bnge_filter.c | 775 ++++++++++++ .../net/ethernet/broadcom/bnge/bnge_filter.h | 129 ++ .../ethernet/broadcom/bnge/bnge_hwrm_lib.c | 170 ++- .../ethernet/broadcom/bnge/bnge_hwrm_lib.h | 8 + .../net/ethernet/broadcom/bnge/bnge_netdev.c | 513 +++++--- .../net/ethernet/broadcom/bnge/bnge_netdev.h | 94 +- .../net/ethernet/broadcom/bnge/bnge_resc.c | 128 +- .../net/ethernet/broadcom/bnge/bnge_resc.h | 1 + .../net/ethernet/broadcom/bnge/bnge_vnic.c | 378 ++++++ .../net/ethernet/broadcom/bnge/bnge_vnic.h | 96 ++ 13 files changed, 3115 insertions(+), 320 deletions(-) create mode 100644 drivers/net/ethernet/broadcom/bnge/bnge_filter.c create mode 100644 drivers/net/ethernet/broadcom/bnge/bnge_filter.h create mode 100644 drivers/net/ethernet/broadcom/bnge/bnge_vnic.c create mode 100644 drivers/net/ethernet/broadcom/bnge/bnge_vnic.h -- 2.52.0
