Subject: [dpdk-stable] [PATCH 19.11 1/2] net/ena: enable multi-segment in Tx offload flags
Date: Wed, 11 Aug 2021 11:51:44 +0200 [thread overview]
Message-ID: <20210811095145.1846-1-mk@semihalf.com> (raw)
From: Ghalem Boudour <ghalem.boudour@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")
