I try to understand how the ip rule add fwmark
works together with mask
,
for example:ip rule
command show the following rule:
100: from all fwmark 0xd00/0xffffff00 lookup 6017
so if there a packet with mark "0xd70" arrives, it will try to match the mark in the ip rules, but how the "0xd70" is calucated with the fwmark and the mask "0xd00/0xffffff00"?
Thank you!
