Default option is "0", possible values 0-255.
The HSR capable device can operate in two modes of operations - Doubly Attached Node for HSR (DANH) and RedBOX (HSR-SAN). The latter one allows connection of non-HSR aware device(s) to HSR network. This node is called SAN (Singly Attached Network) and is connected via INTERLINK network device. This patch adds support for passing information about the INTERLINK device, so the Linux driver can properly setup it. Signed-off-by: Lukasz Majewski <lukma@denx.de> --- Changes for v2: - Rebase the patch on top of iproute2-next/main repo - Replace matches() with strcmp() when interlink - Use print_color_string() instead of just print_string() Changes for v3: - Add proper description to ip/iplink.c and man/man8/ip-link.8.in --- ip/iplink.c | 4 ++-- ip/iplink_hsr.c | 18 +++++++++++++++++- man/man8/ip-link.8.in | 5 +++++ 3 files changed, 24 insertions(+), 3 deletions(-)
