Support multiple domain numbers for each uds socket used in HA phc2sys. The ha_domainNumber option is an interface setting to configure the domain number for an uds socket. It ranges from 0 to 127. If the ha_domainNumber is not configured for a given interface, the global domainNumber setting is used. Test plan: PASS: Verify use of ha_domainNumber configuration in manual configuration. Failure path: domain number match PASS: Verify that phc2sys fails to start if domain number doesn't match ptp4l instance parameter. Regression: PASS: Verify use of global domain number in manual configuration. PASS: Verify auto configuration uses global domain number.

Subject: [PATCH 19/48] Introduce error codes for the run_pmc method.
|
|
|
|
The run_pmc function is used by several of the PMC agent methods, but it
|
|
breaks the pattern of returning zero on success. However, the user facing
|
|
PMC agent methods will need to conform to the return code convention used
|
|
throughout the stack.
|
|
|
|
In order to migrate to proper return codes, this patch replaces the hard
|
|
coded result values with macros so that the interface methods can translate
|
|
them to the required semantics of zero on success.
