+Subject: [PATCH] net: remove NETIF_F_GSO_FRAGLIST from NETIF_F_GSO_SOFTWARE
+
+Several drivers set NETIF_F_GSO_SOFTWARE, but mangle fraglist GRO packets
+in a way that they can't be properly segmented anymore.
+In order to properly deal with this, remove fraglist GSO from
+NETIF_F_GSO_SOFTWARE and switch to NETIF_F_GSO_SOFTWARE_ALL (which includes
+fraglist GSO) in places where it's safe to add.
