This patchset introduces a new per-port bonding option: `ad_actor_port_prio`. It allows users to configure the actor's port priority, which can then be used by the bonding driver for aggregator selection based on port priority. This provides finer control over LACP aggregator choice, especially in setups with multiple eligible aggregators over 2 switches. v3: a) add comments when init slave port_priority (Jonas Gorski) b) rename ad_lacp_port_prio to lacp_port_prio (Jay Vosburgh) v2: a) set default bond option value for port priority (Nikolay Aleksandrov) b) fix __agg_ports_priority coding style (Nikolay Aleksandrov) c) fix shellcheck warns Hangbin Liu (3): bonding: add support for per-port LACP actor priority bonding: support aggregator selection based on port priority selftests: bonding: add test for LACP actor port priority Documentation/networking/bonding.rst | 18 +++- drivers/net/bonding/bond_3ad.c | 31 +++++++ drivers/net/bonding/bond_netlink.c | 16 ++++ drivers/net/bonding/bond_options.c | 37 ++++++++ include/net/bond_3ad.h | 2 + include/net/bond_options.h | 1 + include/uapi/linux/if_link.h | 1 + .../selftests/drivers/net/bonding/Makefile | 3 +- .../drivers/net/bonding/bond_lacp_prio.sh | 93 +++++++++++++++++++ tools/testing/selftests/net/forwarding/lib.sh | 24 ----- tools/testing/selftests/net/lib.sh | 24 +++++ 11 files changed, 224 insertions(+), 26 deletions(-) create mode 100755 tools/testing/selftests/drivers/net/bonding/bond_lacp_prio.sh -- 2.50.1
