Question about /usr/include/netdevice.h

Hello all,

I am new at this so bare with me...

Inside /usr/include/linux/netdevice.h, there is a #define for MAX_ADDR_LEN which is currently set to a value of "7" in 2.4. I am working on an implementation where the hardware address of the media needs be larger than 7 bytes. What is the process by which I would have to go through to get this value changed to something larger than 7 bytes, if I so desired ?

Thanks,

Joe Golio
