eCPRI (packet fronthaul)

eCPRI packet-based fronthaul: the common header (protocol revision, C bit, message type, payload size), the message types (IQ Data, Bit Sequence, Real-Time Control, Generic Data Transfer, Remote Memory Access, One-Way Delay Measurement, Remote Reset, Event Indication), PC_ID/SEQ_ID stream identification and concatenation of several eCPRI messages in one Ethernet frame. Split out of vip-cpri because they are not one product: classic CPRI is constant-bit-rate over a vendor SerDes and genuinely PHY-gated, while eCPRI rides ordinary Ethernet or UDP/IP and is pure packet protocol — exactly the layer this catalog builds well, and the same call that unparked NVMe and Interlaken. This repo already carries the Ethernet layer beneath it (gmac, eth_t1_mac, tsn_switch, eth_pfc).

Key Features

• eCPRI common header: revision, C (concatenation) bit, message type, payload size
• The eight defined message types, including One-Way Delay Measurement
• PC_ID / SEQ_ID stream identification and sequence tracking
• Concatenation of multiple eCPRI messages inside one Ethernet frame
