    tcp: __tcp_hdrlen() helper

    [ Upstream commit d9b3fca27385eafe61c3ca6feab6cb1e7dc77482 ]

    tcp_hdrlen is wasteful if you already have a pointer to struct tcphdr.
    This splits the size calculation into a helper function that can be
    used if a struct tcphdr is already available.

I got an error in kernel 4.1.51 and checked it. I haven't checked between 4.1.50 and 4.4.114.

Why are you running these 4.1 kernels? That series is no longer supported upstream, so not terribly inclined to spend a lot of time supporting it here either. If you want the compat layer fixed, please open a pull request...

For asus routers. RT-AC86U is running 4.1.27 and RT-AX88U is running 4.1.51.

It's enough to fix it personally and use it, but there was an error, so I left an issue.
