[PATCH] mii-tool: make the 'No MII transceiver present!' message more clear

[Antony Pavlov]

Suppose you have two network controllers.
The first one is ENC28J60 (it is in low power mode
after start) the second one is always-enabled eth1.

As ENC28J60 is in low power mode before enc28j60_eth_open()
is called. ENC28J60's mii traceiver is in low power mode too
so the mii traceiver's register are inaccessable.

Here is a sample log just after barebox start:

  barebox:/ miitool
  miibus0: registered phy as /dev/phy0
    No MII transceiver present!.
  miibus1: registered phy as /dev/phy1
  phy1: eth1: negotiated 100baseTx-FD, link ok
  barebox:/ miitool
    No MII transceiver present!.
  phy1: eth1: negotiated 100baseTx-FD, link ok

The 'No MII transceiver present!.' message is confusing here.

This patch fixes the problem so the miitool output
looks like this:

  barebox:/ miitool
  phy0: spieth0:  No MII transceiver present!.
  phy1: eth1: negotiated 100baseTx-FD, link ok
