Hi Ghalem, This patch enables announcement of the DEV_TX_OFFLOAD_MULTI_SEGS capability, but still the application may not request this offload. As ENA PMD currently assumes all the mbufs may have multiple segments (and we don't have fast-path for the other cases), I suggest overwriting this flag in the ena_dev_configure(), similar to what we're doing with the DEV_RX_OFFLOAD_RSS_HASH flag.
