Thin flattened-port wrappers under protocols/packetizer/wrappers/ so cocotb can drive and observe the existing packetizer RTL through standard AXI Stream ports without embedding stimulus in VHDL: - AxiStreamBytePackerWrapper - AxiStreamPacketizerWrapper / AxiStreamDepacketizerWrapper - AxiStreamPacketizer2Wrapper / AxiStreamDepacketizer2Wrapper - AxiStreamPacketizer2LoopbackWrapper (end-to-end packetize/depacketize topology)

Python cocotb tests and shared helpers under tests/protocols/packetizer/ covering byte-width packing, packetizer/depacketizer payload round trips, packetizer2/depacketizer2 framing, CRC and EOFE/error handling, link-drop behavior, sequence-number wrap, and packetizer2 loopback recovery.

Description
Adds focused cocotb regression coverage for the AXI Stream packetizer family, including byte packing, packetizer/depacketizer, packetizer2/depacketizer2, CRC/error handling, link-drop behavior, loopback behavior, and sequence wrap handling.
Details
This packetizer-focused slice adds thin VHDL wrappers under
protocols/packetizer/wrappers/so cocotb can drive and observe the existing RTL through flattened AXI Stream ports without embedding stimulus in VHDL. The wrappers cover:AxiStreamBytePackerAxiStreamPacketizerandAxiStreamDepacketizerAxiStreamPacketizer2andAxiStreamDepacketizer2The new Python regression support under
