Commit Message

Jacob Keller Aug. 5, 2022, 11:41 p.m. UTC 
The dl_argv_parse_put function is used to extract arguments from the
command line and convert them to the appropriate netlink attributes. This
function is a combination of calling dl_argv_parse and dl_put_opts.

A future change is going to refactor dl_argv_parse to check the kernel's
netlink policy for the command. This requires issuing another netlink
message which requires calling dl_argv_parse before
mnlu_gen_socket_cmd_prepare. Otherwise, the get policy command issued in
dl_argv_parse would overwrite the prepared buffer.

This conflicts with dl_argv_parse_put which requires being called after
mnlu_gen_socket_cmd_prepare.

Remove dl_argv_parse_put and replace it with appropriate calls to
dl_argv_parse and dl_put_opts. This allows us to ensure dl_argv_parse is
called before mnlu_gen_socket_cmd_prepare while dl_put_opts is called
afterwards.
