I'm not philosophically opposed to Line mode support, but I am
concerned about providing a userspace interface that's not getting tested
or used or otherwise not fit for purpose. I copied you on the other email
regarding the specific deficiencies so I won't reiterate them here.

Perhaps it's fortunate that userspace didn't pick this up; otherwise,
this interface would be cast in stone.

Peter Hurley
