Thanks for your patch. I tested it in the hope that it would fix the following issue: https://lore.kernel.org/u-boot/caj+vnu2u9w2nrt6hf1caeq_56sdqviuezudd1iyopdf1cna...@mail.gmail.com/ but I still get wget corruption when loading large files multiple times in a row. Would you happen to have any suggestions? Thanks
