4xx_enet.c: Fix GCC 4.6 build warnings
Fix: 4xx_enet.c: In function 'ppc_4xx_eth_init': 4xx_enet.c:875:6: warning: variable 'ethgroup' set but not used [-Wunused-but-set-variable] I used "__maybe_unused" here intentionally, since all other alternatives to fix this compilation warning would result in more ifdef's. Signed-off-by: Stefan Roese <sr@denx.de>
