Code commented out and NIC is working OK. Strange.
eth0: DSPCFG accepted after 0 usec.
eth0: link up.
eth0: Setting full-duplex based on negotiated link capability.
dspcfg = 0x00000000  np->dspcfg = 0x00005060
dspcfg = 0x00000000  np->dspcfg = 0x00005060

dspcfg = 0x00000000  np->dspcfg = 0x00005060

One problem solved in mean time :-)
