- 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 Original-commit: 7f86724ec3387f75d39d683b2ac5f5152e714c74
