lan743x: Remove MAC Reset from initialization
The MAC Reset was noticed to erase important EEPROM settings. It is also unnecessary since a chip wide reset was done earlier in initialization, and that reset preserves EEPROM settings. There for this patch removes the unnecessary MAC specific reset. Signed-off-by: Bryan Whitehead <Bryan.Whitehead@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
