From f43308fa0c7834d9707a2c212591275d1e095e50 Mon Sep 17 00:00:00 2001 From: Joe Hershberger Date: Tue, 3 Jul 2018 19:36:42 -0500 Subject: [PATCH] net: Read bootfile from env on netboot_common() Instead of depending on a env callback for bootfile, read it explicitly. We do this because the bootfile can be specified on the command line and if it is, we will overwrite the internal variable. If a netboot_common() is called again with no bootfile parameter, we want to use the one in the environment.
