From cb2c57112432d5c77f97ea6320973d02beebf3ee Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 15 Jan 2021 17:47:45 +0800 Subject: vxlan: add NETIF_F_FRAGLIST flag for dev features Some protocol HW GSO requires fraglist supported by the device, like SCTP. Without NETIF_F_FRAGLIST set in the dev features of vxlan, it would have to do SW GSO before the packets enter the driver, even when the vxlan dev and lower dev (like veth) both have the feature of NETIF_F_GSO_SCTP. So this patch is to add it for vxlan.
