Subject: [PKT_SCHED]: Fix qdisc return code.
X-Git-Tag: firefly_0821_release~39394^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=29f1df6cc1c3ee3530939f0e38d80a9b50645ba5;p=firefly-linux-kernel-4.4.55.git

[PKT_SCHED]: Fix qdisc return code.

The mapping between TC_ACTION_SHOT and the qdisc return codes is better
suited to NET_XMIT_BYPASS so as not to confuse TCP
