If instead the device is running in VEPA mode,\nthe packets will go through the encryption engine and out the\nMAC/PHY as normal, and get \"hairpinned\" as needed by the switch.\n\nSo let's not block IPsec offload when in VEPA mode. To get\nthere with the ixgbe device, use the handy 'bridge' command:\n\tbridge link set dev eth1 hwmode vepa\n\nSigned-off-by: Shannon Nelson <shannon.nelson@oracle.com>\n---\n drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c | 4 +++-\n 1 file changed, 3 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c b/drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c\nindex fd1b054..4d77f42 100644\n--- a/drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c\n+++ b/drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c\n@@ -4,6 +4,7 @@\n #include \"ixgbe.h\"\n #include <net/xfrm.h>\n #include <crypto/aead.h>\n+#include <linux/if_bridge.h>\n \n #define IXGBE_IPSEC_KEY_BITS 160\n static const char aes_gcm_name[] = \"rfc4106(gcm(aes))\";\n@@ -693,7 +694,8 @@ static int ixgbe_ipsec_add_sa(struct xfrm_state *xs)\n \t} else {\n \t\tstruct tx_sa tsa;\n \n-\t\tif (adapter->num_vfs)\n+\t\tif (adapter->num_vfs &&\n+\t\t adapter->bridge_mode != BRIDGE_MODE_VEPA)\n \t\t\treturn -EOPNOTSUPP;\n \n \t\t/* find the first unused index */\n", "prefixes": [] }
