From 67fde5d58cd43d129a979e918ec9cd5d2e2fbcfb Mon Sep 17 00:00:00 2001

Subject: [PATCH 08/15] net: airoha: Move REG_GDM_FWD_CFG() initialization in
airoha_dev_init()
Move REG_GDM_FWD_CFG() register initialization in airoha_dev_init
routine. Moreover, always send traffic PPE module in order to be
processed by hw accelerator.
This is a preliminary patch to enable netfilter flowtable hw offloading
on EN7581 SoC.
