Change subject: osmo-bts-trx: set don't-fragment flag on all TRXD packets
......................................................................


Patch Set 5:

> If you enable the DF bit, you are actively breaking existing situations that 
> are working for the user (with fragmentation overhead).

or to be more precise: If you want to enable DF, then you have to implement [in 
your application] some path-mtu-discovery to dynamically at runtime detect the 
MTU and then scale your UDP payload sizes to stay below it.

In the absence of this, one could possibly introduce a VTY parameter.

In the end, as stated above, over loopback it doesn't matter.
