smsc95xx: generate random MAC address once, not every ifup
The smsc95xx driver currently generates a new random MAC address every time the interface is brought up. This makes it impossible to override using the standard `ifconfig hw ether` approach. Past patches tried to make the MAC address a module parameter or base it off the die ID, but it seems to me much simpler (and hopefully less controversial) to stick with the current random generation scheme, but allow the user to change the address. This patch does exactly that - it moves the random address generation from smsc95xx_reset() into smsc95xx_bind(), so that it is done once on module load, not on every ifup. The user can then override this using the standard mechanisms. Applies against 2.6.35 and linux-2.6 head. Signed-off-by: Bernard Blackham <b-omap@largestprime.net> Signed-off-by: David S.
