[PATCH 1/5] net/hns3: fix incorrect index to look up table in NEON Rx

[Dongdong Liu]

From: Huisong Li <lihuisong at huawei.com>

In hns3_recv_burst_vec(), the index to get packet length and data
size are reversed. Fortunately, this doesn't affect functionality
because the NEON Rx only supports single BD in which the packet
length is equal to the date size. Now this patch fixes it to get
back to the truth.

Fixes: a3d4f4d291d7 ("net/hns3: support NEON Rx")
