    net-timestamp: move timestamp flags out of sk_flags · b9f40e21

    sk_flags is reaching its limit. New timestamping options will not fit.
    Move all of them into a new field sk->sk_tsflags.
    
    Added benefit is that this removes boilerplate code to convert between
    SOF_TIMESTAMPING_.. and SOCK_TIMESTAMPING_.. in getsockopt/setsockopt.
    
    SOCK_TIMESTAMPING_RX_SOFTWARE is also used to toggle the receive
    timestamp logic (netstamp_needed). That can be simplified and this
    last key removed, but will leave that for a separate patch.

    The u16 in sock can be moved into a 16-bit hole below sk_gso_max_segs,
    though that scatters tstamp fields throughout the struct.
