-- Purpose: Assembles the RDMA header at snk_in.sop
-- Description:
-- The hdr_fields_slv output is set one st_clk cycle after snk_in.sop and will
-- contain the RoCEv2 (RDMA over Converged Ethernet v2) header information for
-- contain the RoCEv2 (RDMA over Converged Ethernet v2) header information for
-- the corresponding data frame.
-- Remark
-- . The incoming data frame on snk_in should consist of at least 2 clock cycles.
-- i.e. two consecutive 1 cycle frames (sop + eop on the same clock cycle)
-- i.e. two consecutive 1 cycle frames (sop + eop on the same clock cycle)
-- without a gap inbetween is not supported.
