+Ethernet autonegotiation needs some time to complete. Instead of
+delaying the boot process in all cases, we just start the
+autonegotiation process when U-Boot comes up and that is all. Most
+likely, it will complete by the time the network transfer is
+attempted for the first time. In the worst case, if a transfer is
+attempted before the autonegotiation is complete, just a single
+packet would be lost resulting in a single timeout error, and then
+the transfer would proceed normally. So the time that we would have
+lost unconditionally waiting for the autonegotiation to complete, we
+have to wait only if the file transfer is started immediately after
+reset. We've verified that this works for all the clock
+configurations.
