- cache the result in NMPlatformPrivate. No need to call the virtual function every time. The result is not ever going to change. - if we are unable to detect support, assume support. Those features were added quite a while ago to kernel, we should default to "support". Note, that we detect support based on the presence of the absence of certain netlink flags. That means, we will still detect no support. The only moment when we actually use the fallback value, is when we didn't encounter an RTM_NEWADDR or AF_INET6-IFLA_AF_SPEC message yet, which would be very unusual, because we fill the cache initially and usually will have some addresses there. - for no strong reason, track "undetected" as numerical value zero, and "support"/"no-support" as 1/-1. We already did that previously for _support_user_ipv6ll, so this just unifies the implementations. The minor reason is that this puts @_support_user_ipv6ll to the BSS section and allows us to omit initializing priv->check_support_user_ipv6ll_cached in platforms constructor. - detect _support_kernel_extended_ifa_flags also based on IPv4 RTM_NEWADDR messages. Originally, extended flags were added for IPv6, and later to IPv4 as well. Once we see an IPv4 message with IFA_FLAGS, we know we have support. |
