Re: [Patch] MdeModulePkg/DeviceManagerUiLib: Fix the network device MAC display issue

["Dong, Eric" <eric.dong@intel.com>]

Jiaxin,

Thanks to help to fix this issue. 

We'd better define new STR_FORM_NETWORK_DEVICE_TITLE_HEAD for L" Network Device " instead of hard code in the code.

Thanks,
Eric

Subject: [Patch] MdeModulePkg/DeviceManagerUiLib: Fix the network device MAC display issue

Network device tile (STR_FORM_NETWORK_DEVICE_TITLE) is dynamic adjusted according the different MAC value. So, the string value shouldn't be treated as a constant string (Network Device). Otherwise, the display will be incorrect.

Reproduce: Device Manager->Network Device List, select to enter MAC, then to press ESC back to previous page, then re-enter, found each enter/ESC operation, the MAC address display +1.
