This adds several features to the SystemVerilog Eth/IPv4/UDP transport
adaptor including:
- Compat register
- NODE_INST register
- Capabilities register
- KV map access for custom routing on RX data paths
- CHDR header removal for raw payloads to be sent over UDP
Also adds xport_adapter_ctrl.py, which allows controlling the new
registers.

- Detect dropped words at the dispatch level. This prevents
an overflow on CHDR from block CPU.
- Dropped packets are recorded as CPU or CHDR drop count
- Refactor to put chdr_xport_adapter.sv in different clock
domain to improve timing
- Unwrinkle tkeep/trailing transitions

The rnfoc/xport section is refactored in System Verilog to allow the
following improvements
(1) CPU_W - Sets the size of the c2e and e2c pipes. This can be run
at a different clock rate than the main ethernet pipe
(2) CHDR_W - Sets the size of the v2e and e2v pipes. This can be run
at a different clock rate than the main ethernet pipe
(3) ENET_W - Sets the size of the eth_tx and eth_rx pipes.
eth_interface_tb runs traffic from e2c,e2v,v2e,c2e simultaneously
against the original xport_sv implementation, and against the new
implementation with widths of 64/128/512. A chdr_management node
info request queries the port info of the node0 in the eth_interface.
eth_ifc_synth_test.sv can be compiled with the make xsim target to test
out the size of various configurations.
