[dpdk-dev] [PATCH v2 1/9] net/hns3: fix the shift of DMA address in Rx/Tx queue

["Min Hu (Connor)" <humin29@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

The patch obtains the upper 32 bits of the Rx/Tx queue DMA address in one
step instead of two steps.

Fixes: bba636698316 ("net/hns3: support Rx/Tx and related operations")
