[dpdk-stable] [PATCH 19.11 1/2] net/ena: enable multi-segment in Tx offload flags

[Michal Krawczyk]

From: Ghalem Boudour <ghalem.boudour at 6wind.com>

[ upstream commit 3e7008459df969611fb7aa3b885a949515ac0b49 ]

The DPDK ENA driver does not provide multi-segment tx offload capability.
Let's add DEV_TX_OFFLOAD_MULTI_SEGS to ports offload capability by
default, and always set it in dev->data->dev_conf.txmode.offload.

This flag in not listed in doc/guides/nics/features/default.ini, so
ena.ini does not need to be updated.

Fixes: 1173fca25af9 ("ena: add polling-mode driver")
