[Linuxptp-devel] [PATCH v3 1/5] config: Added network namespace config parameters

[Anders S. <and...@es...>]

This patch adds configuration parameters for network namespace.
These parameters are only needed when configuring interfaces in
different namespaces than each other. Otherwise the ptp4l program
can be started directly in correct namespace.
