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.
