+Subject: scripts: download.pl: retry download using filename
+
+With this commit, the download script will try downloading source files
+using the filename instead of the url-filename in case the previous
+download attempt using the url-filename failed.
+
+This is required, as the OpenWrt sources mirrors serve files using the
+filename files might be renamed to after downloading. If the original
+mirror for a file where url-filename and filename do not match goes
+down, the download failed prior to this patch.
+
+Further improvement can be done by performing this only for the
+OpenWrt sources mirrors.
