The function hclge_parse_capability() uses too many if statement, and

Subject: [PATCH net-next 5/7] net: hns3: don't config TM DWRR twice when set ETS

The function hclge_tm_dwrr_cfg() will be called twice in function
hclge_ieee_setets() when map_changed is true, the calling flow is
hclge_ieee_setets()
hclge_map_update()
| hclge_tm_schd_setup_hw()
| hclge_tm_dwrr_cfg()
hclge_notify_init_up()
hclge_tm_dwrr_cfg()

It is no need to call hclge_tm_dwrr_cfg() twice actually, so just
return after calling hclge_notify_init_up().

Currently, function hclge_check_port_speed() uses switch/case statement
to get speed bit according to speed. To reuse this part of code and
improve code readability and maintainability, add a new function
hclge_get_speed_bit() to get speed bit according to map relationship
of speed and speed bit defined in array speed_bit_map.
