From 723bbfd8bdb76012a3da937c7499cf3c0b111dd5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] kernel_netlink.c: don't include <linux/if_bridge.h>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Including <linux/if_bridge.h> causes the inclusion of <linux/in6.h>,
which defines 'struct in6_addr', also defined in <netinet/in.h>, causing
a build failure with the musl C library:

In order to address this, this patch removes the <linux/if_bridge.h>
inclusion, and instead defines BRCTL_GET_BRIDGES to the appropriate
value if it's not provided by the C library.
