Description

Steps to reproduce:
1, ./setup.sh --machine qemux86-64 --dl-layers --distro wrlinux-cgl --templates feature/cut
2, . oe-init-build-env build
3, bitbake wrlinux-image-glibc-cgl
4, boot the target with [runqemu qemux86-64 wrlinux-image-glibc-cgl nographic bootparams="selinux=0 enforcing=0" qemuparams="-m 2048"]
use tnftp to login in the vsftp server as below:
# tnftp 127.0.0.1
Connected to 127.0.0.1.

then the ftp connection breaks.
