Blackfin EMAC driver: Fix Ethernet communication bug (dupliated and lost packets)
Fix Ethernet communication bug(dupliated and lost packets) in RMII PHY mode- dont call mac_disable and mac_enable during 10/100 REFCLK changes - mac_enable screws up the DMA descriptor chain Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
