From 709ffbe19b777e8fc952e2fdcfd8e6f50c8ef08c Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 29 May 2020 02:25:41 +0200 Subject: net: remove indirect block netdev event registration Drivers do not register to netdev events to set up indirect blocks anymore. Remove __flow_indr_block_cb_register() and __flow_indr_block_cb_unregister(). The frontends set up the callbacks through flow_indr_dev_setup_block() Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S.
