Re: [PATCH 7/7] net/lwip: wget: integrate struct wget_info into wget code

On 11/6/24 13:04, Adriano Cordova wrote:

Each wget request now fills the struct wget_info. Also, the efi bootdevice is now set conditionally to the set_bootdevice variable in wget_info and a buffer size check is performed if check_buffer_size is set.
