get_rxd_bnum has not been used, so this patch removes

[Huazhong Tan]

From: Yunsheng Lin <linyunsheng@huawei.com>

hnae3_set_bit and hnae3_set_field masks the data before setting
the field or bit, which is unnecessary because the data is already
zero initialized.

[Patch net-next 07/12] net: hns3: remove hnae3_get_bit in data path

[Huazhong Tan]

From: Yunsheng Lin <linyunsheng@huawei.com>

The hnae3_get_bit uses hnae3_get_field, and hnae3_get_field
masks the data, which is unnecessary in data path.

[Patch net-next 09/12] net: hns3: enable VF VLAN filter for each VF when initializing

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

For revision 0x21, the switch of VF VLAN filter is per function.
It's necessary to enable VF VLAN filter for each VF when initializing.
Otherwise, VF will be able to receive broadcast packets with unknown
VLAN when PF enters promisc mode.

Fixes: 64d114f0a750 ("net: hns3: Add egress/ingress vlan filter for revision 0x21")

[Patch net-next 10/12] net: hns3: fix get VF RSS issue

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

For revision 0x20, VF shares the same RSS config with PF.
In original codes, it always return 0 when query RSS hash
key for VF. This patch fixes it by return the hash key
got from PF.

[Patch net-next 11/12] net: hns3: fix setting of the hns reset_type for rdma hw errors

[Huazhong Tan]

From: Shiju Jose <shiju.jose@huawei.com>

Presently the hns reset_type for the roce errors is set
in the hclge_log_and_clear_rocee_ras_error function.
This function is also called to detect and clear roce errors
while enabling the rdma error interrupts. However there is no hns
reset requested for this case. This can cause issue of wrong
reset_type used with subsequent hns reset as the
reset_type set in the above case was not cleared.

This patch moves setting of hns reset_type for the roce errors from
hclge_log_and_clear_rocee_ras_error function
to hclge_handle_rocee_ras_error.

Fixes: 630ba007f475 ("net: hns3: add handling of RDMA RAS errors")
