net: hsr: Send supervisory frames to HSR network with ProxyNodeTable data
This patch provides support for sending supervision HSR frames with
MAC addresses stored in ProxyNodeTable when RedBox (i.e. HSR-SAN) is
enabled.
Supervision frames with RedBox MAC address (appended as second TLV)
are only send for ProxyNodeTable nodes.
This patch series shall be tested with hsr_redbox.sh script.
