Hi Detlev,
Please try this one. I used the git-format-patch for its creation.
Thanks,
Michael

Subject: [PATCH] The patch fixes the bug of partial intialization of
global network parameters.
Upon u-boot's start up the first ping command causes a failure of the
consequent TFTP transfers. It happens in the recently added mechanism of
NetLoop initialization where initialization of global network parameters is
separated in the NetInitLoop routine which is called per env_id change.
Thus, ping request will initialize the network parameters necessary for ping
operation only, afterwards the env_changed_id will be set to the env_id
that will prevent all following initialization requests from other protocols.
The problem is that the initialized by ping subset of network parameters is not
sufficient for other protocols and particularly for TFTP
which requires the NetServerIp also.
