[PATCH net-next 01/12] netfilter: br_netfilter: Unmask upper DSCP bits in br_nf_pre_routing_finish()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Unmask upper DSCP bits when calling ip_route_output() so that in the
future it could perform the FIB lookup according to the full DSCP value.
