eCPRI protocol has unified format layout for the variants, over ETH layer (including .1Q) and UDP layer. The common header of the message has 4 bytes fixed length, and the message payload layers are different based on the type field. Now only type #0, #2 and #5 will be supported, and 2 bytes are needed. When creating the flex parser, the header will be extended to 8 bytes and 2 DW samples are needed. The 1st DW starts from offset 0 and will be used for the type field of the common header. The 2nd DW starts from offset 4 and will be used for the physical channel ID, real-time control ID or measurement ID fields. The parser will be created once a flow with eCPRI item is observed for the first time. After creating, it will remain in the system and HW until the device is stopped. Right now, there is no need to destroy the eCPRI flex parser after the last flow with eCPRI item is destroyed. This is to get rid of the alternate states of creating and destroying eCPRI flex parser with a single eCPRI flow.
