Yes, sir!

Is it just slow or you loose packets as I do while TFTP something? I
observe that on S3E reference with Petalogix image, my own image -
doesn't matter - as well as on my S2E based board. However when uClinux
is up and running, I can TFTP without any visible packet loss. So I
assumed that must be u-boot emac_lite driver problem (I'm using 1.1.4
version from Petalogix distro).
