Effectively, this drops them.\nIn this patch series, we aim to address this behaviour by adding MAC,VLAN\nto complement what MAC-only filters do to select packets for loopback.\n\nTo reproduce the issue have an E810 ($pfa) connected to another adapter\n($pfb), then:\n\n # echo 2 >/sys/class/net/$pfa/device/sriov_numvfs\n # ip l set $pfa vf 0 vlan 4\n # ip l set $pfa vf 1 vlan 7\n # ip l set $pfa_vf0 netns $pfa_vf0_netns up\n # ip l set $pfa_vf1 netns $pfa_vf1_netns up\n # ip netns exec $pfa_vf0_netns ip a add 10.0.0.1/24 dev $pfa_vf0\n # ip netns exec $pfa_vf1_netns ip a add 10.0.0.2/24 dev $pfa_vf1\n\nAnd for the $pfb:\n\n # echo 2 >/sys/class/net/$pfb/device/sriov_numvfs\n # ip l set $pfb vf 0 trust on spoof off vlan 4\n # ip l set $pfb vf 1 trust on spoof off vlan 7\n # ip l add $br type bridge\n # ip l set $pfb_vf0 master $br up\n # ip l set $pfb_vf1 master $br up\n # ip l set $br up\n\nWe expect $pfa_vf0 to be able to reach $pfa_vf1 through the $br on\nthe link partner. Instead, ARP is unable to resolve 10.0.0.2/24.\nARP request is fine because it's broadcastd and bounces off $br, but\nARP reply is stuck in the internal switch because the destination MAC\nmatches $pfa_vf0 and filter restricts it to the loopback.\n\nIn testing I used: ip utility, iproute2-6.1.0, libbpf 1.3.0\n\nChanges in v4:\n - Removed \"ice: do not check for zero mac when creating mac filters\"\n patch.\n\nChanges in v3:\n - Improve structure of reproduction description in cover letter.\n - LB_LAN masks and values no longer rely on boolean promotion.\n - ice_fill_sw_info() deals with u8 the entire time instead of building\n building lb_en and lan_en values at the end from booleans.\n - Refer to reproduction in cover letter in current 4/7.\n - Fixed some slip-ups \"this patch\" and \"this commit\" in commit\n messages across the series. I did not consider this change for\n reviewed-by drop.\n\nChanges in v2:\n - Use FIELD_GET et al. when handling fi.lb_en and fi.lan_en.\n - Rename /LB_LAN/ s/_MASK/_M/ because one of uses would need to break\n line.\n - Close open parenthesis in ice_vsi_update_bridge_mode() description.\n - Explain returns in ice_vsi_update_bridge_mode().\n\nv3: https://lore.kernel.org/intel-wired-lan/20260120103440.892326-1-jakub.slepecki@intel.com/T/\nv2: https://lore.kernel.org/intel-wired-lan/20251125083456.28822-1-jakub.slepecki@intel.com/T/\nv1: https://lore.kernel.org/intel-wired-lan/20251120162813.37942-1-jakub.slepecki@intel.com/T/\n\nJakub Slepecki (6):\n ice: in dvm, use outer VLAN in MAC,VLAN lookup\n ice: allow creating mac,vlan filters along mac filters\n ice: allow overriding lan_en, lb_en in switch\n ice: update mac,vlan rules when toggling between VEB and VEPA\n ice: add functions to query for vsi's pvids\n ice: in VEB, prevent \"cross-vlan\" traffic from hitting loopback\n\nMichal Swiatkowski (1):\n ice: add mac vlan to filter API\n\n drivers/net/ethernet/intel/ice/ice_fltr.c | 104 ++++++++++++++-\n drivers/net/ethernet/intel/ice/ice_fltr.h | 10 +\n drivers/net/ethernet/intel/ice/ice_lib.c | 56 ++++++++\n drivers/net/ethernet/intel/ice/ice_lib.h | 2 \n drivers/net/ethernet/intel/ice/ice_main.c | 56 ++++++--\n drivers/net/ethernet/intel/ice/ice_switch.c | 83 ++++++++---\n drivers/net/ethernet/intel/ice/ice_switch.h | 24 ++-\n drivers/net/ethernet/intel/ice/ice_vf_lib.c | 8 -\n drivers/net/ethernet/intel/ice/ice_vlan_mode.c | 12 +\n 9 files changed, 306 insertions(+), 49 deletions(-)" }
