Well yeah, one can use it to handle existing commands instead of
IFLA_NAME.
But why does it rule out separate commands? I think it is cleaner than
to put everything in poor setlink messages :/ The fact that we would
need to add "OP" to the setlink message just feels of. Other similar
needs may show up in the future and we may endup in ridiculous messages
like:
SETLINK
IFLA_NAME eth0
IFLA_ATLNAME_LIST (nest)
IFLA_ALTNAME_OP add
IFLA_ALTNAME somereallylongname
IFLA_ALTNAME_OP del
IFLA_ALTNAME somereallyreallylongname
IFLA_ALTNAME_OP add
IFLA_ALTNAME someotherreallylongname
IFLA_SOMETHING_ELSE_LIST (nest)
IFLA_SOMETHING_ELSE_OP add
...
IFLA_SOMETHING_ELSE_OP del
...
IFLA_SOMETHING_ELSE_OP add
...
I don't know what to think about it. Rollbacks are going to be pure hell :/
