2018-07-11gso: support UDP/IPv4 fragmentationJiayu Hu
This patch adds GSO support for UDP/IPv4 packets. Supported packets may include a single VLAN tag. UDP/IPv4 GSO doesn't check if input packets have correct checksums, and doesn't update checksums for output packets (the responsibility for this lies with the application). Additionally, UDP/IPv4 GSO doesn't process IP fragmented packets. UDP/IPv4 GSO uses two chained MBUFs, one direct MBUF and one indrect MBUF, to organize an output packet. The direct MBUF stores the packet header, while the indirect mbuf simply points to a location within the original packet's payload. Consequently, use of UDP GSO requires multi-segment MBUF support in the TX functions of the NIC driver. If a packet is GSO'd, UDP/IPv4 GSO reduces its MBUF refcnt by 1. As a result, when all of its GSOed segments are freed, the packet is freed automatically. Signed-off-by: Jiayu Hu <> Acked-by: Xiao Wang <>

2018-01-30lib: build with mesonBruce Richardson
Add non-EAL libraries to DPDK build. The compat lib is a special case, along with the previously-added EAL, but all other libs can be build using the same set of commands, where the individual files only need to specify their dependencies, source files, header files and ABI versions.
