+-- Author: R. van der Walle
+-- Purpose: Provide AXI-4-stream interfaces + standard avalon MM interfaces for
+--          eth_tester.vhd such that it can be used to create a Vivado IP block.
+-- Description:
+-- . The rdma_generator_eth_tester_wrapper uses axi4_stream_dp_bridge to convert the dp
+--   sosi/siso interfaces of the eth_tester into AXI4-Stream interfaces.
+-- . In order for this component to be suitable as a Vivado IP, the ports are
+--   exclusively STD_LOGIC(_VECTOR) where the widths are hard-coded as demanded
+--   by the Vivado IP creator (only supports VHDL-93).
+-- Remark
+-- . Avalon is used for all MM interfaces, which can be bridged to AXI4-Lite in
+--   vivado using the AXI AMM Bridge IP.

+  -- hdr_field_sel bit selects where the hdr_field value is set:
+  -- . 0 = data path controlled, value is set in data path, so field_default()
+  --       is not used.
+  -- . 1 = MM controlled, value is set via MM or by the field_default(), so any
+  --       data path setting in eth_tester.vhd is not used.
+  -- Remarks:
+  -- . For constant values it is convenient to use MM controlled, because then
+  --   the field_default() is used that can be set here in
+  --   c_rdma_generator_hdr_field_arr.
+  -- . For reserved values it is convenient to use MM controlled, because then
+  --   in future they could still be changed via MM without having to recompile
+  --   the FW.
+  -- . Typically only use data path controlled if the value has to be set
+  --   dynamically, so dependent on the state of the FW.
+  -- . If a data path controlled field is not set in the FW, then it defaults
+  --   to 0 by declaring hdr_fields_in_arr with all 0. Hence e.g. udp_checksum
+  --   = 0 can be achieve via data path and default hdr_fields_in_arr = 0 or
+  --   via MM controlled and field_default(0).
