Functions
void	AuRouteTableInitialise ()
	AuRouteTableInitialise – initialise the kernel route table.
AuRouteEntry *	AuRouteTableCreateEntry ()
	AuRouteTableCreateEntry – create a new route table entry and return.
void	ip_ntoa (const uint32_t src)
void	AuRouteTableAdd (AuRouteEntry *entry)
	AuRouteTableAdd – add an entry to route table. Allows default route (dest==0 && netmask==0). Replaces an existing entry with the same dest/netmask/ifname.
void	AuRouteTableDelete (AuRouteEntry *entry)
	AuRouteTableDelete – delete an entry from route table (including default 0/0).
int	AuRouteSetFlag4 (const char *ifname, uint32_t dest, uint32_t netmask, int up)
