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 include/linux/netdev_features.h | 2 +- net/core/dev.c | 6 ++++++ 2 files changed, 7 insertions(+), 1 deletion(-) -- 2.7.4
