Subject: vxlan: set mac_header correctly in GPE mode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8be0cfa4d352167df508acd571eb19afd8a2ce93;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

vxlan: set mac_header correctly in GPE mode

For VXLAN-GPE, the interface is ARPHRD_NONE, thus we need to reset
mac_header after pulling the outer header.

v2: Put the code to the existing conditional block as suggested by
    Shmulik Ladkani.
