diag: Add support for header untagging
This patch provides the support for segregate different PD data onto
separate buffers and then onto its own data stream based on received
diag private id header from the peripheral data packets.
This patch adds a new feature mask supporting the feature and
a new IOCTL querying the support of the feature.
