From: Andreas Roeseler <redacted> [ Upstream commit e32ea44c7ae476f4c90e35ab0a29dc8ff082bc11 ] Including <linux/in.h> and <netinet/in.h> in the dependencies breaks compilation of trinity due to multiple definitions. <linux/in.h> is only used in <linux/icmp.h> to provide the definition of the struct in_addr, but this can be substituted out by using the datatype __be32.
