[Qemu-devel] [PATCH] tftp: fake support for netascii protocol |

From: Vincent Bernat <address@hidden>
Some network equipments are requesting a file using the netascii
protocol and this is not configurable. Currently, qemu's tftpd only
supports the octet protocol. This commit makes it accept the netascii
protocol as well but do not perform the requested transformation (LF ->
CR,LF) as it would be far more complex. The current implementation is
good enough. A user has always the choice to preencode the served file
correctly.
