mainline inclusion from mainline-v5.15-rc1 commit aec35aecc3ccc822b358e2594ff70ff54245261e category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4BY3P CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
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.
