====================
net: hns3: add some cleanups & optimizations

This patchset includes some cleanups and optimizations for the HNS3
ethernet driver.

[patch 1/8] removes unused and unnecessary structures.

[patch 2/8] uses a ETH_ALEN u8 array to replace two mac_addr_*
field in struct hclge_mac_mgr_tbl_entry_cmd.

[patch 3/8] optimizes the barrier used in the IO path.

[patch 4/8] introduces macro ring_to_netdev() to get netdevive
from struct hns3_enet_ring variable.

[patch 5/8] makes struct hns3_enet_ring to be cacheline aligned

[patch 6/8] adds a minor cleanup for hns3_handle_rx_bd().

[patch 7/8] removes linear data allocating for fraglist SKB.

[patch 8/8] clears hardware error when resetting.
====================
