Merge branch 'renesas-eth-fixes'
Sergei Shtylyov says:
====================
Fix some dubious code in the Renesas Ethernet drivers
Here's a set of 2 patches against DaveM's 'net.git' repo. While initializing
EMAC the code tries to respect the duplex mode both programmed into ECMR and
stored in its own private data -- this just can't be right.
[1/2] ravb: stop reading ECMR in ravb_emac_init()
[2/2] sh_eth: stop reading ECMR in sh_eth_dev_init()
====================
