Update cicn-plugin for vpp v17.04 (from v17.01)Vpp-plugin-v17.04
1. Changes for cicn-plugin to build under v17.04:
- update build files to v17.04, including
- no longer need/want plugin to include dpdk headers (though
still link in dpdk plugin)
- vpp include changes
- relocation of vpe.api.h
- relocation of pneum.h
- for modprobe, replace igb_uio with uio_pci_generic
- vnet/ip/udp.h => vnet/udp/udp.h
- update cicn vpp plugin registration per vpp changes
- use new VLIB_PLUGIN_REGISTER() macro
- delete no-loger-supported vlib_plugin_register() function,
moving contents of latter to cicn_init
- remove sm->ethernet_main, which was not used and is no longer part of
plugin boilerplate.
- cicn_api_test_plugin.so (plugin for vpp_api_test)
- update per 17.04 updated requirements:
vat_api_hookup => cicn_vat_api_hookup
- buffering/cloning changes needed for building
- CICN_FEATURE_VPP_VLIB_CLONING hard-coded enabled and removed,
- CICN_FEATURE_DPDK_RTEMBUF_CLONING removed
- Small indentation updates from vpp checkstyle.sh
2. Updates for new vlib_buffer_attach_clone() API now exported by vpp
- remove code to manage rte_mbuf: cicn plugin now longer depends
on dpdk being present.
- remove use of indirect header for cloned cs entry: new scheme
supports having hdr buffer point directly to shared buffer rather
that requiring hdr buffer to poitn to indirect header that
points to cs buffer
- cicn_rte_mbuf_inlines.h replaced by much smaller cicn_infra_inlines.h
- report new characteristic of whether cloning replication is enabled
- "cicn show internal" (dbg cli), "cicn_api_node_params_get"
(vpp_api_test)
- update output accordingly
- cicn_show: other tweaks to output
3. In node.c, in code for dropping possibly multiple buffers
- delete ifdef'd-out code block for dropping using the drop node
[this codepath possibly had buffer problems.]
- retain code that instead drops by freeing buffers directly.
[this codepath has been robust with respect to buffer management]
