Summary

When displaying a vendor specified logpage, currently we have to specify the vendor name. if the user did not provide the vendor name, we can use the controller's vid to choose the formatting function.

Test Plan

query vendor specify logpage without specify vendor name, check the display output.

A more proper approach would be to provide the vendor id when registering a logpage.
later it can be used to match the controller's id.

By "match", do you mean "select" or "choose"? If so, I would use either of those instead for clarity.
