From 449312c1c0c686ad28c51e6429d8bbdd13812b10 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 15 Jun 2018 10:29:27 +0200 Subject: net: Prefer command line arguments We can call commands like dhcp and bootp without arguments or with explicit command line arguments that really should tell the code where to look for files instead. Unfortunately, the current code simply overwrites command line arguments in the dhcp case with dhcp values. This patch allows the code to preserve the command line values if they were set on the command line. That way the semantics are slightly more intuitive. The reason this patch does that by introducing a new variable is that we can not rely on net_boot_file_name[0] being unset, as today it's completely legal to call "dhcp" and afterwards run "tftp" and expect the latter to repeat the same query as before. I would prefer not to break that behavior in case anyone relies on it.
