From 14bfb13f0ed525ed117b5d1f3e77e7c0a6be15de Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 19 Jul 2019 18:20:16 +0200 Subject: net: flow_offload: add flow_block structure and use it This object stores the flow block callbacks that are attached to this block. Update flow_block_cb_lookup() to take this new object. This patch restores the block sharing feature.
