ipv6: Refactor update of IPv6 flowi destination address for srcrt (RH) option
There are more than a dozen occurrences of following code in the IPv6 stack: if (opt && opt->srcrt) { struct rt0_hdr *rt0 = (struct rt0_hdr *) opt->srcrt; ipv6_addr_copy(&final, &fl.fl6_dst); ipv6_addr_copy(&fl.fl6_dst, rt0->addr); final_p = &final; } Replace those with a helper. Note that the helper overrides final_p in all cases. This is ok as final_p was previously initialized to NULL when declared. Signed-off-by: Arnaud Ebalard <arno@natisbad.org> Signed-off-by: David S. Miller <davem@davemloft.net>
