Subject: [RFC net-next 1/2] udp: add NETIF_F_GSO_UDP_L4 to NETIF_F_SOFTWARE_GSO
Date: Wed, 8 Jul 2020 11:48:55 +0800	[thread overview]
Message-ID: <1594180136-15912-2-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1594180136-15912-1-git-send-email-tanhuazhong@huawei.com>

Add NETIF_F_SOFTWARE_GSO to the the list of GSO features with
a software fallback.  This allows UDP GSO to be used even if
the hardware does not support it, and for virtual device such
as VxLAN device, this UDP segmentation will be postponed to
physical device.
