From: Gabriel Paubert <[EMAIL PROTECTED]> In this driver, the default ethernet address is first set by by calling eth_port_uc_addr_get() which reads the relevant registers of the corresponding port as initially set by firmware. However that function used the port_num field accessed through the private area of net_dev before it was set.
The result was that one board I have ended up with the unicast address set to 00:00:00:00:00:00 (only port 1 is connected on this board). The problem appeared after commit 84dd619e4dc3b0b1c40dafd98c90fd950bce7bc5. This patch fixes the bug by setting mp->port_num prior to calling eth_port_uc_get_addr().
