[PATCH net-next,v3 08/11] drivers: net: use flow block API

Pablo Neira Ayuso
2019-07-08T16:06:56Z

This patch updates flow_block_cb_setup_simple() to use the flow block API.
Several drivers are also adjusted to use it.

This patch introduces the per-driver list of flow blocks to account for
blocks that are already in use.

Remove tc_block_offload alias.

v3: incorrect list name variables in several drivers - Jakub Kicinski.
