driver inclusion category: feature bugzilla: 4472
-----------------------------------------------------------------------
Obtaining optical module information is time-consuming. If the user frequently acquires, it will affect the firmware to process other commands. To prevent such events, the firmware will actively report the optical module information to the driver when it is idle. Obtained from the driver cache information. When the user obtains through the command, directly obtain from the information saved by the driver.
