Subject: net: Kill plain NET_XMIT_BYPASS.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cc6533e98a7f3cb7fce9d740da49195c7aa523a4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net: Kill plain NET_XMIT_BYPASS.

dst_input() was doing something completely absurd, looping
on skb->dst->input() if NET_XMIT_BYPASS was seen, but these
functions never return such an error.

And as a result plain ole' NET_XMIT_BYPASS has no more
references and can be completely killed off.
