Lukasz Majewski 5055cccfc2 net: hsr: Provide RedBox support (HSR-SAN) ... Introduce RedBox support (HSR-SAN to be more precise) for HSR networks. Following traffic reduction optimizations have been implemented: - Do not send HSR supervisory frames to Port C (interlink) - Do not forward to HSR ring frames addressed to Port C - Do not forward to Port C frames from HSR ring - Do not send duplicate HSR frame to HSR ring when destination is Port C The corresponding patch to modify iptable2 sources has already been sent: https://lore.kernel.org/netdev/20240308145729.490863-1-lukma@denx.de/T/ Testing procedure (veth and netns): ----------------------------------- One shall run: linux-vanila/tools/testing/selftests/net/hsr/hsr_redbox.sh (Detailed description of the setup one can find in the test script file). Testing procedure (real hardware): ---------------------------------- The EVB-KSZ9477 has been used for testing on net-next branch (SHA1: 5fc68320c1). Ports 4/5 were used for SW managed HSR (hsr1) as first hsr0 for ports 1/2 (with HW offloading for ksz9477) was created. Port 3 has been used as interlink port (single USB-ETH dongle). Configuration - RedBox (EVB-KSZ9477): if link set lan1 down;ip link set lan2 down ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 supervision 45 version 1 ip link add name hsr1 type hsr slave1 lan4 slave2 lan5 interlink lan3 supervision 45 version 1 ip link set lan4 up;ip link set lan5 up ip link set lan3 up ip addr add 192.168.0.11/24 dev hsr1 ip link set hsr1 up Configuration - DAN-H (EVB-KSZ9477): ip link set lan1 down;ip link set lan2 down ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 supervision 45 version 1 ip link add name hsr1 type hsr slave1 lan4 slave2 lan5 supervision 45 version 1 ip link set lan4 up;ip link set lan5 up ip addr add 192.168.0.12/24 dev hsr1 ip link set hsr1 up This approach uses only SW based HSR devices (hsr1). -------------- ----------------- ------------ DAN-H Port5 | <------> | Port5 | | Port4 | <------> | Port4 Port3 | <---> | PC | | (RedBox) | | (USB-ETH) EVB-KSZ9477 | | EVB-KSZ9477 | | -------------- ----------------- ------------ Signed-off-by: Lukasz Majewski <lukma@denx.de> Signed-off-by: Paolo Abeni <pabeni@redhat.com>		2024-04-26 12:04:43 +02:00
