From: Murphy Yang Date: Thu, 1 Apr 2021 03:23:32 +0000 (+0000) Subject: net/i40e: fix flow director config after flow validate X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4a072ad434426ebfb5a6120858a971b54e7d2204;p=dpdk.git net/i40e: fix flow director config after flow validate The configuration of FDIR input set should not be set during flow validate. It should be set when flow create. Fixes: fe5d0e85b713 ("net/i40e: fix flow director flex configuration") Fixes: 15018d79f0be ("net/i40e: add FDIR support for GTP-C and GTP-U") Cc: stable@dpdk.org Signed-off-by: Murphy Yang Acked-by: Beilei Xing --- diff --git a/drivers/net/i40e/i40e_ethdev.h b/drivers/net/i40e/i40e_ethdev.h index faf6896fbc..cdf1c2fe1f 100644 --- a/drivers/net/i40e/i40e_ethdev.h +++ b/drivers/net/i40e/i40e_ethdev.h @@ -631,6 +631,7 @@ struct i40e_fdir_flow_ext { uint8_t raw_id;
