> 
> 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.
