Revision c09c8a27b9baa417864b9adc3228b10ae5eeec93 authored by Florian Klink on 15 November 2020, 22:45:09 UTC, committed by Jakub Kicinski on 18 November 2020, 01:02:03 UTC
Checking for ifdef CONFIG_x fails if CONFIG_x=m.

Use IS_ENABLED instead, which is true for both built-ins and modules.

Otherwise, a
> ip -4 route add 1.2.3.4/32 via inet6 fe80::2 dev eth1
fails with the message "Error: IPv6 support not enabled in kernel." if
CONFIG_IPV6 is `m`.

In the spirit of b8127113d01e53adba15b41aefd37b90ed83d631.
