Like Ethernet,\nIB defines a layered protocol (Physical, Link, Network, Transport\nLayers). IB provides native support for RDMA(Remote DMA), an\nextension of the DMA that allows direct access to remote host\nmemory without CPU intervention. IB network requires NICs and\nswitches to support the IB protocol.\n\nRoCE(RDMA over Converged Ethernet) is a network protocol that\nallows RDMA to run on Ethernet. RoCE encapsulates IB packets on\nEthernet and has two versions, RoCEv1 and RoCEv2. RoCEv1 is an\nEthernet link layer protocol, IB packets are encapsulated in the\nEthernet layer and use Ethernet type 0x8915. RoCEv2 is an internet\nlayer protocol, IB packets are encapsulated in UDP payload and\nuse a destination port 4791, The format of the RoCEv2 packet is\nas follows:\n ETH + IP + UDP(dport 4791) + IB(BTH + ExtHDR + PAYLOAD + CRC)\n\nBTH(Base Transport Header) is the IB transport layer header, RoCEv1\nand RoCEv2 both contain this header. This patch introduces a new\nRTE item to match the IB BTH in RoCE packets. One use of this match\nis that the user can monitor RoCEv2's CNP(Congestion Notification\nPacket) by matching BTH opcode 0x81.\n\nThis patch also adds the testpmd command line to match the RoCEv2\nBTH. Usage example:\n\n testpmd> flow create 0 group 1 ingress pattern\n eth / ipv4 / udp dst is 4791 / ib_bth opcode is 0x81\n dst_qp is 0xd3 / end actions queue index 0 / end\n\nSigned-off-by: Dong Zhou <dongzhou@nvidia.com>\nAcked-by: Ori Kam <orika@nvidia.com>\nAcked-by: Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru>\n\nv2:\n -
