Mystery Phenonmenon

Sometimes ping sometimes not and the speed is slower sometimes:

It was ethmb9.c which was inconsistent in ping that sometimes it pings and sometimes it does not ping immediately after or permanently after restarting. It was twice or thrice in ten times. And, even it pings, the speed is comparatively slow with other cases.

It was purely the distance between the setting of Speed/Duplex settings in MCR register and starting the Tx/Rx. It needs sometimes once set the mode to stabilize. So, I made the setting of MCR at starting of lan_start() and start settings at the end of it.
