NAME

       rte_gso_ctx

SYNOPSIS

       #include <rte_gso.h>

   Data Fields
       struct rte_mempool * direct_pool
       struct rte_mempool * indirect_pool
       uint64_t flag

Field Documentation

   struct rte_mempool* direct_pool
       MBUF pool for allocating direct buffers, which are used to store packet headers for GSO segments.

       Definition at line 38 of file rte_gso.h.

   struct rte_mempool* indirect_pool
       MBUF pool for allocating indirect buffers, which are used to locate packet payloads for GSO segments. The
       indirect buffer doesn't contain any data, but simply points to an offset within the packet to segment.

       Definition at line 42 of file rte_gso.h.

   uint64_t flag
       flag that controls specific attributes of output segments, such as the type of IP ID generated (i.e.
       fixed or incremental).

       Definition at line 48 of file rte_gso.h.

   uint32_t gso_types
       the bit mask of required GSO types. The GSO library uses the same macros as that of describing device TX
       offloading capabilities (i.e. RTE_ETH_TX_OFFLOAD_*_TSO) for gso_types.

       For example, if applications want to segment TCP/IPv4 packets, set RTE_ETH_TX_OFFLOAD_TCP_TSO in
       gso_types.

       Definition at line 52 of file rte_gso.h.

   uint16_t gso_size
       maximum size of an output GSO segment, including packet header and payload, measured in bytes. Must
       exceed RTE_GSO_SEG_SIZE_MIN.

       Definition at line 61 of file rte_gso.h.
