Hardware timestamping support (PTP) on Rx requires extended buffer descriptors, double the size of normal Rx descriptors. On the current controller revision only the timestamping offload requires extended Rx descriptors. Since Rx timestamping can be turned on/off at runtime, make Rx ring allocation configurable at runtime too. As a result, the static config option FSL_ENETC_HW_TIMESTAMPING can be dropped and the extended descriptors can be used only when Rx timestamping gets activated. The extension has the same size as the base descriptor, making the descriptor iterators easy to update for the extended case.

There are Time-Sensitive Network(TSN) capabilities(802.1Qbv/802.1Qci
|
|
/802.1Qbu etc.) supported by ENETC. These TSN capabilities can be set
|
|
enable/disable from user space via Qos commands(tc). In the kernel
|
|
side, it can be loaded by Qos driver. Currently, it is only support
|
|
taprio(802.1Qbv) and Credit Based Shaper(802.1Qbu).
