From a7f80189e41c96c0c6210e9198a31859c91eb3e5 Mon Sep 17 00:00:00 2001 From: Edward Cree Date: Fri, 13 Apr 2018 19:17:49 +0100 Subject: [PATCH] sfc: pass the correctly bogus filter_id to rps_may_expire_flow() When we inserted an ARFS filter for ndo_rx_flow_steer(), we didn't know what the filter ID would be, so we just returned 0. Thus, we must also pass 0 as the filter ID when calling rps_may_expire_flow() for it, and rely on the flow_id to identify what we're talking about.
