From 483a3966b570529a910dc2a02deac0036e642309 Mon Sep 17 00:00:00 2001 From: Slava Shwartsman Date: Mon, 3 Apr 2017 13:13:51 +0300 Subject: IB/core: Introduce drop flow specification This flow steering specification identifies flow for drop by the HW. If user create a flow only with the drop specification, then all the packets that hit this flow will be dropped, otherwise the HW will drop only the packets that match the other L2/L3/L4 specifications.
