CONFIG_NET_GPTP_BMCA_PRIORITY1
¶
BMCA priority1 value
Type: int
Help¶
The priority1 attribute of the local clock. It is used in the Best Master Clock selection Algorithm (BMCA), lower values take precedence. The default value is 255 if the device is non grand master capable, and 248 if it is GM capable. See Chapter 8.6.2.1 of IEEE 802.1AS for a more detailed description of priority1. Note that if the system is non GM capable, then the value 255 is used always and this setting is ignored.
