I just tried to apply this with "git am" to the current v4.19 -stable
branch and it failed.

[davem@...alhost linux-stable]$ git am --signoff diff

error: patch failed: net/core/dev.c:5083

When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
