* DO *NOT* *EVER* CHANGE THESE - they *MUST* match what the Tethering mainline module provides!
*
* You cannot even change them in sync, since newer module must work on older Android T releases.
*
* You could with difficulty, uprevs of the bpfloader, api detection logic in mainline, etc,
* change this in Android U or later, but even that is a very bad idea and not worth the hassle.
*
*
* Mainline Tethering module on T+ is expected to make available to netd (for use by
* BandwidthController iptables initialization code) four xt_bpf programs at the following
* locations:
