Enable USE_AS_BUFF on packet gate to allow many packets to be buffered.
This reduces latency when several small packets are sent out close
together.

Fix the TUSER width for some buses in eth_ipv4_chdr_adapter. This
allows wider CHDR widths to be used with 10 GbE.
Original-commit: f0ed58f7518410fc174a6356c072dfb21e3de253
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.

The NET_CHDR_W parameter tells the transport adapter what CHDR width
is used in transport packets, such as Ethernet packets. By default the
CHDR width used by the transport and RFNoC core will be the same. The
NET_CHDR_W parameter can be used in situations where the RFNoC core
expects a CHDR width from the transport adapter that is different from
that used over the network. In this situation, the transport adapter
will rewrite the CHDR packets so that each side gets the expected CHDR
width.

- 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.
