From 806ab081dc9ae3ea313ae9e471ee1c97c7a9e2ad Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Fri, 29 Apr 2022 20:32:37 +0200 Subject: netlink: swap byteorder for host-endian concat data All data must be passed in network byte order, else matching won't work respectively kernel will reject the interval because it thinks that start is after end This is needed to allow use of 'ppp*' in interval sets with concatenations.
