Commit Message

Arnd Bergmann April 23, 2019, 3:11 p.m. UTC 
With all isdn4linux hardware drivers gone, this is only a wrapper around
CAPI to support old user space. However, from looking at the mailing
list, it seems that the last time anyone asked about it was in 2014,
when the upgrade from a linux-2.4 installation failed, and mISDN was
suggested as a replacement.

The largest public ISDN network (Deutsche Telekom) was shut down 2018,
which must have drastically reduced the number of legacy installations,
if there were any that managed to get isdn4linux to work with a linux-4.x
kernel at all.

When we last discussed removing i4l in 2016, Karsten Keil suggested
revisiting this in 2018. I guess this is overdue.
