From: Ghalem Boudour <redacted>
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")
