Subject: [BRIDGE]: optimize frame pass up
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d5513a7d32de721a9e396c2b32cf277d5cef5fb6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[BRIDGE]: optimize frame pass up

The netfilter hook that is used to receive frames doesn't need to be a
stub.  It is only called in two ways, both of which ignore the return
value.
