This set of patches has been originally sent to to netdev@ two weeks
ago.

The idea is the following: ip_options->is_data field is checked only
inside ip_options_compile when opt != NULL. This is possible only on the
following codepath:
    ip_options_get_finish
        opt->is_data = 1;
        ip_options_compile(opt, NULL)

ip_options->is_data is not a part of user<->kernel interface and can be
removed.

Regards,
	Den
