Subject: [dpdk-dev] [PATCH v1 2/3] net/hinic/base: fix the problem of LRO
Date: Fri, 16 Jul 2021 17:54:29 +0800	[thread overview]
Message-ID: <23f4b28a1d1c8b3b3f1b74665030f6a6a4c84b9d.1626429126.git.zhouguoyang@huawei.com> (raw)
In-Reply-To: <cover.1626429126.git.zhouguoyang@huawei.com>

The rx queue must config as ceq disable, and must set msix
state disable. Otherwise when lro is enable, there will be
problems with packet aggregation because of firmware.

Fixes: 9d02f40d6503 ("net/hinic: fix LRO")
Cc: stable@dpdk.org
