Subject: [PATCH net-next 5/5] net: hns3: remove unnecessary frag list checking in hns3_nic_net_xmit()

The skb_has_frag_list() in hns3_nic_net_xmit() is redundant, since
skb_walk_frags() includes this checking implicitly.

Subject: [PATCH net-next 3/5] net: hns3: modify an incorrect error log in hclge_mbx_handler()

When handling HCLGE_MBX_GET_LINK_STATUS, PF will return the link
status to the VF, so the error log of hclge_get_link_info() is
incorrect.

Subject: [PATCH net-next 2/5] net: hns3: remove a duplicated printing in hclge_configure()

Since hclge_get_cfg() already has error print, so hclge_configure()
should not print error when calling hclge_get_cfg() fail.

You may want to spell out 'state' instead of 'stat' in patch 3, stat is
often used as abbreviation of statistic. But that's a nit pick, up to
you:
