net: fib_rules: Add DSCP mask attribute
Add an attribute that allows matching on DSCP with a mask. Matching on
DSCP with a mask is needed in deployments where users encode path
information into certain bits of the DSCP field.
Temporarily set the type of the attribute to 'NLA_REJECT' while support
is being added.
