net: hns3: fix incorrect hw rss hash type of rx packet

Currently, the HNS3 driver reports the rss hash type
of each packet based on the rss hash tuples set. It
always reports PKT_HASH_TYPE_L4, without checking the
type of current packet. It's incorrect.
Fixes it by reporting it base on the packet type.

Fixes: 796640778c26 ("net: hns3: support RXD advanced layout")
Fixes: 232fc64b6e62 ("net: hns3: Add HW RSS hash information to RX skb")
Fixes: ea4858670717 ("net: hns3: handle the BD info on the last BD of the packet")

net: hns3: fix incorrect type of argument in declaration of function hclge_comm_get_rss_indir_tbl

The argument rss_ind_tbl_size is type u16 in function definition of
hclge_comm_get_rss_indir_tbl(), but it is set to type __le16 in function
declaration by mistake, so fix it.

net: hns3: create new set of common rss init APIs for PF and VF reuse

This patch creates new set of common rss init APIs for PF and VF rss
module. Subfunctions called by rss init process are also created include
rss tuple configuration and rss indirect table configuration.

These new common rss init APIs will be used to replace the old PF and VF
rss init APIs in next patches.

net: hns3: create new set of common rss set APIs for PF and VF module

Currently, hns3 PF and VF rss module have two sets of rss set APIs to
configure rss. There is no need to keep two sets of these same APIs.

So this patch creates new set of common rss set APIs for PF and VF reuse.
These new APIs will be used to unify old APIs in next patches.

net: hns3: create new set of common rss get APIs for PF and VF rss module

The PF and VF rss get APIs are almost the same espect the suffixes of API
names. These same impementions bring double development and bugfix work.

So this patch creates new common rss get APIs for PF and VF rss module.
Subfunctions called by rss query process are also created(e.g. rss tuple
conversion APIs).

These new common rss get APIs will be used to replace PF and VF old rss
APIs in next patches.

net: hns3: create new rss common structure hclge_comm_rss_cfg

Currently PF stores its rss parameters in vport structure. VF stores rss
configurations in hclgevf_rss_cfg structure. Actually hns3 rss parameters
are same beween PF and VF. The two set of rss parameters are redundent and
may add extra bugfix work.

So this patch creates new common rss parameter struct(hclge_comm_rss_cfg)
to unify PF and VF rss configurations.

These new structures will be used to unify rss configurations in PF and VF
rss APIs in next patches.
