Subject: [PATCH 1/2] net/bonding: fix bond3 and bond4 process mbuf fast free
Date: Tue, 8 Nov 2022 16:40:37 +0800 [thread overview]
Message-ID: <20221108084038.25136-2-lihuisong@huawei.com> (raw)
In-Reply-To: <20221108084038.25136-1-lihuisong@huawei.com>
The RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE offload can't be used in bonding
mode Broadcast and mode 8023AD. Currently, bonding driver forcibly removes
from the dev->data->dev_conf.txmode.offloads and processes as success in
bond_ethdev_configure(). But this still cause that rte_eth_dev_configure()
fails to execute because of the failure of validating Tx offload in the
eth_dev_validate_offloads(). So bonding driver shouldn't modify offloads
in dev->data->dev_conf.txmode and should return error in this case.
Fixes: 18c41457cbae ("net/bonding: fix mbuf fast free usage")
