From a532e2f2e52277635fac79cdbe4e6b5b51166de4 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 15 Mar 2018 15:07:09 +0100 Subject: [PATCH] net: Only access network devices after init In the efi_loader main loop we call eth_rx() occasionally. This rx function might end up calling into devices that haven't been initialized yet, potentially resulting in a lot of transfer timeouts. Instead, let's make sure the ethernet device is actually initialized before reading from or writing to it.
