Add support of Ethernet link bonding utilizing DPDK link bonding
poll mode driver library. The bonded interfaces to be created on VPP startup is specified in the dpdk section of startup.conf or qn.conf, using DPDK EAL command. Following is an example of a dpdk section white listing PCI addressses of 4 ethernet interfacess to be under VPP control plus two bonded interface and the PCI addresses of the slaves in each: dpdk { socket-mem 1024,1024 dev 0000:0f:00.0 dev 0000:10:00.0 dev 0000:11:00.0 dev 0000:12:00.0 vdev eth_bond0,mode=2,slave=0000:0f:00.0,slave=0000:11:00.0,xmit_policy=l34 vdev eth_bond1,mode=2,slave=0000:10:00.0,slave=0000:12:00.0,xmit_policy=l34 } Note that only balance XOR (mode 2) is supported and "xmit_policy=l34" specifies to use layer 3 SIP/DIP and layer 4 Sport/Dport for load balance. Using "xmit_policy=l2" for SMAC/DMAC or "xmit_policy=l23" for SMAC/DMAC and SIP/DIP should also work. Change-Id: Iaf6438686fa20cce893cb5a823b76e2886b4360b Signed-off-by: John Lo <loj@cisco.com>
