[PATCH net-next 4/5] ipv6: help __ip6_finish_output() inlining

From: Pavel Begunkov
Date: Thu Apr 28 2022 - 07:01:34 EST


There are two callers of __ip6_finish_output(), both are in
ip6_finish_output(). We can combine the call sites into one and handle
return code after, that will inline __ip6_finish_output().

Note, error handling under NET_XMIT_CN will only return 0 if
__ip6_finish_output() succeded, and in this case it return 0.
Considering that NET_XMIT_SUCCESS is 0, it'll be returning exactly the
same result for it as before.
