u-boot-megous/drivers/net/ne2000.c
Axel Lin a62cd29c98 net: Use ARRAY_SIZE at appropriate places 
Use ARRAY_SIZE instead of having similar implementation in each drivers.
The NUMELEMS defined in drivers/net/npe/include/IxOsalTypes.h is not used
at all, so this patch removes it instead of converting it to use ARRAY_SIZE.
