HandoverPacketHolderUe¶

//
// Manages uplink packet buffering during handover at the user equipment.
// Temporarily holds packets from the network layer when handover is in progress.
// Whether the UE is attached at all is read from a mirror of RRC's stack attachment
// ledger, which RRC pushes on every handover event (see BearerManagement).
// Releases buffered packets to the protocol stack once handover completes successfully.
