ifconfig eth0 up failure on new cLinux embedded

I tested the network with directed test software and it appeared to work. Now when I try to bring up cLinux implementation with ifconfig, I get: IOCTL 0x8914 failed: No such device. Does this mean the mdio driver cannot reach the ethernet phy ie the phy driver is working but not configured properly? I modified the broadcom.c file to include my BCM5221 and it appears to be correct. Just looking for clarification on what the IOCTL failure is telling me.

ioctl 8914: Operation not permitted.

Found the issue was a failure of the processor to communicate with the LAN Phy. This was due to the phy internal pullup being insufficient to operate at the 2.5mhz mdio bus speed. Added additional pullup and system started working.
