The discussion from 2007 is the last one I could find on lore that has
useful information on when and why this was not removed in the past.
The driver was scheduled from a 2005 removal in 2004, but not removed
because both Red Hat and SuSE relied on the feature in their distros.
From what I could find out, this continued to be the case in Red Hat
Enterprise Linux 6 and SUSE Linux Enterprise server 11 that were
supported between 2009 and 2020, but the following versions dropped
the support.
