Subject: [RFC net-next 0/2] net: two updates related to UDP GSO

There are two updates related to UDP GSO.
#1 adds NETIF_F_GSO_UDP_L4 to NETIF_F_SOFTWARE_GSO, then the virtual
device can postpone its UDP GSO to physical device, as extention to
commit 83aa025f535f ("udp: add gso support to virtual devices").
#2 disable UDP GSO feature when CSUM is disabled. Currently, when
disabled CSUM, sending a UDP packet who needs segmentation will will
fail, but from user-space the UDP GSO feature is enabled, so disble
UDP GSO feature when CSUM disabled just like what TSO does now.

Huazhong Tan (2):
  udp: add NETIF_F_GSO_UDP_L4 to NETIF_F_SOFTWARE_GSO
  net: disable UDP GSO feature when CSUM is disabled
