Subject: openvswitch: Compute checksum in skb_gso_segment() if needed
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=09c5e6054e206ecf13945f50711856a5cb2d5de1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

openvswitch: Compute checksum in skb_gso_segment() if needed

The copy & csum optimization is no longer present with zerocopy
enabled. Compute the checksum in skb_gso_segment() directly by
dropping the HW CSUM capability from the features passed in.
