[v3,02/60] service: Sanity check the 'type' param in '__connman_service_wispr_start'.

Commit Message

Grant Erickson Dec. 21, 2023, 10:34 p.m. UTC

This adds sanity checking for the 'type' parameter in
'__connman_service_wispr_start'. In addition, it adds an explicit
conditional test for the 'CONNMAN_IPCONFIG_TYPE_IPV6'.

Both of these ensure that neither 'CONNMAN_IPCONFIG_TYPE_ALL' or
'CONNMAN_IPCONFIG_TYPE_UNKNOWN' trigger a WISPr start but, instead,
error out.
