64-bit operations.\n+;\n+; Notes:\n+;\n+; 1. The 128-bit fields are always stored in network byte order (NBO), even when these fields are\n+; meta-data fields, so the instructions like \"mov\" or \"movh\" that accept a 128-bit operand and\n+; a 64-bit (or lesser size) operand require the latter to be also stored in NBO, i.e. it must\n+; be a header field. Hence, the 64-bit upper_half and lower_half fields below are stored in a\n+; header, and not in meta-data.\n+;\n+; 2. To write a IPv6 address, the lower half (bits 63-0) must be written first using the mov\n+; instruction, as it also fills the upper half (bits 127-64) with zeros, and then the upper\n+; half must me written using the movh instruction, as the movh instruction does not change the\n+; lower half.\n+\n+//\n+// Headers.\n+//\n+struct ethernet_h {\n+\tbit<48> dst_addr\n+\tbit<48> src_addr\n+\tbit<16> ethertype\n+}\n+\n+struct ipv6_h {\n+\tbit<32> version_traffic_class_flow_label\n+\tbit<16> payload_length\n+\tbit<8> next_header\n+\tbit<8> hop_limit\n+\tbit<128> src_addr\n+\tbit<128> dst_addr\n+}\n+\n+struct sandbox_h {\n+\tbit<64> upper_half\n+\tbit<64> lower_half\n+}\n+\n+header ethernet instanceof ethernet_h\n+header ipv6 instanceof ipv6_h\n+header tmp instanceof sandbox_h\n+\n+//\n+// Meta-data.\n+//\n+struct metadata_t {\n+\tbit<32> port\n+}\n+\n+metadata instanceof metadata_t\n+\n+//\n+// Pipeline.\n+//\n+apply {\n+\t//\n+\t// RX and parse.\n+\t//\n+\trx m.port\n+\textract h.ethernet\n+\textract h.ipv6\n+\n+\t//\n+\t// Swap the two halves of the IPv6 source address.\n+\t//\n+\tmovh h.tmp.upper_half h.ipv6.src_addr\n+\tmov h.tmp.lower_half h.ipv6.src_addr\n+\tmov h.ipv6.src_addr h.tmp.upper_half\n+\tmovh h.ipv6.src_addr h.tmp.lower_half\n+\n+\t//\n+\t// De-parse and TX.\n+\t//\n+\temit h.ethernet\n+\temit h.ipv6\n+\ttx m.port\n+}\n", "prefixes": [ "3/3" ] }
