Subject: [ftp] User and password URI support for the FTP protocol
X-Git-Tag: v1.0.0-rc1~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=93805d97652b0f7a00028fe1e9ad461a7b5d423c;p=thirdparty%2Fipxe.git

[ftp] User and password URI support for the FTP protocol

The default user and password are used for anonymous FTP by default.
This patch adds support for an explicit user name and password in an FTP
URI:

    imgfetch ftp://user:password@server.com/path/to/file
