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

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")
Cc: stable@dpdk.org
