net:sched: add action inheritdsfield to skbedit
The new action inheritdsfield copies the field DS of IPv4 and IPv6 packets into skb->priority. This enables later classification of packets based on the DS field. v5: *Update the drop counter for TC_ACT_SHOT v4: *Not allow setting flags other than the expected ones. *Allow dumping the pure flags. v3: *Use optional flags, so that it won't break old versions of tc. *Allow users to set both SKBEDIT_F_PRIORITY and SKBEDIT_F_INHERITDSFIELD flags. v2: *Fix the style issue *Move the code from skbmod to skbedit Original idea by Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: Qiaobin Fu <qiaobinf@bu.edu> Reviewed-by: Michel Machado <michel@digirati.com.br> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Reviewed-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Acked-by: Davide Caratti <dcaratti@redhat.com> Signed-off-by: David S.
