So this got merged, and now it *can* work properly. But it doesn't. I
updated to 17.01 and I'm back to 1492-byte PPP.
I think I had also hacked my local build of the module so that not only
would it *permit* a 1508-byte MTU to be set, but it also *defaulted* to
that.
Now, it defaults to 1500 and needs userspace to *set* an MTU of 1508 on
the ptm0 and ptm0.101 VLAN interfaces... and I can't persuade netifd to
do that. I only get full frames if I set the MTU manually.
What am I missing?
