-Subject: [PATCH 1/1] Allow class-e address assignment in ifconfig and early
- boot
-
-While the linux kernel became mostly "class-e clean" a decade ago,
-and most distributions long ago switched to the iproute2 suite
-of utilities, which allow class-e (240.0.0.0/4) address assignment,
-distributions relying on busybox, toybox and other forms of
-ifconfig cannot assign class-e addresses without this kernel patch.
-
-With this patch, also, a boot command line on these addresses is feasible:
-(ip=248.0.1.2::248.0.1.1:255.255.255.0).
-
-While CIDR has been obsolete for 2 decades, and a survey of all the
-userspace open source code in the world shows most IN_whatever macros
-are also obsolete... rather than obsolete CIDR from this ioctl entirely,
-this patch merely enables class-e assignment, sanely.
-
-H/T to Vince Fuller and his original patch here:
