Do you mean I should collect similar hardware parameters setting into one
function?
or
I should set hardware parameters according to hardware feature support version?
For example,
If mac_version == RTL8168DP
dash_ver = 1
else If mac_version == RTL8168DP
dash_ver = 2
if dashver == 1
...
else if dashver == 2
...
