X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6703931c546e6dec0431776fa616d5accd3e7162;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[IPV6]: Fix ipv6 GSO payload length

Fix ipv6 GSO payload length calculation.

The ipv6 payload length excludes the ipv6 base header length and so
must be subtracted.
