From a340c7895a83501df68eb403496cec74bc363157 Mon Sep 17 00:00:00 2001 From: Anjali Singhai Date: Wed, 6 Jan 2016 11:49:28 -0800 Subject: [PATCH] i40e: Enable Geneve offload for FW API ver > 1.4 for XL710/X710 devices This patch makes sure we check the GENEVE offload capable flag before we attempt offload. It also enables the Capability for XL710/X710 devices with FW API version higher than 1.4 Signed-off-by: Anjali Singhai Jain Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher --- drivers/net/ethernet/intel/i40e/i40e_main.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/drivers/net/ethernet/intel/i40e/i40e_main.c b/drivers/net/ethernet/intel/i40e/i40e_main.c index 6e12626afb61..99d7a5c096b5 100644 --- a/drivers/net/ethernet/intel/i40e/i40e_main.c +++ b/drivers/net/ethernet/intel/i40e/i40e_main.c @@ -5354,7 +5354,8 @@ int i40e_open(struct net_device *netdev) vxlan_get_rx_port(netdev); #endif #ifdef CONFIG_I40E_GENEVE - geneve_get_rx_port(netdev); + if (pf->flags & I40E_FLAG_GENEVE_OFFLOAD_CAPABLE) + geneve_get_rx_port(netdev); #endif return 0; @@ -8458,7 +8459,13 @@ static int i40e_sw_init(struct i40e_pf *pf) I40E_FLAG_MULTIPLE_TCP_UDP_RSS_PCTYPE | I40E_FLAG_100M_SGMII_CAPABLE | I40E_FLAG_GENEVE_OFFLOAD_CAPABLE; + } else if ((pf->hw.aq.api_maj_ver > 1) || + ((pf->hw.aq.api_maj_ver == 1) && + (pf->hw.aq.api_min_ver > 4))) { + /* Supported in FW API version higher than 1.4 */ + pf->flags |= I40E_FLAG_GENEVE_OFFLOAD_CAPABLE; } + pf->eeprom_version = 0xDEAD; pf->lan_veb = I40E_NO_VEB; pf->lan_vsi = I40E_NO_VSI; @@ -8672,6 +8679,9 @@ static void i40e_add_geneve_port(struct net_device *netdev, u8 next_idx; u8 idx; + if (!(pf->flags & I40E_FLAG_GENEVE_OFFLOAD_CAPABLE)) + return; + if (sa_family == AF_INET6) return; @@ -8719,6 +8729,9 @@ static void i40e_del_geneve_port(struct net_device *netdev, if (sa_family == AF_INET6) return; + if (!(pf->flags & I40E_FLAG_GENEVE_OFFLOAD_CAPABLE)) + return; + idx = i40e_get_udp_port_idx(pf, port); /* Check if port already exists */ -- 2.20.1
