Subject: [PATCH 16/19] net/hns3: add check for L3 and L4 type
Date: Fri, 30 Sep 2022 15:22:17 +0800	[thread overview]
Message-ID: <20220930072220.20753-17-liudongdong3@huawei.com> (raw)
In-Reply-To: <20220930072220.20753-1-liudongdong3@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

When user set 'L3_SRC/DST_ONLY' or 'L4_SRC/DST_ONLY' to 'rss_hf' and
do not specify the packet type, these types will be set to hardware.
So this patch adds a check for them.

Fixes: 806f1d5ab0e3 ("net/hns3: set RSS hash type input configuration")
Cc: stable@dpdk.org
