de9307c686 netxen: remove old flash check.
Remove flash size check which made sense only for ancient
boards with 1MB flash. The check is based on values read
from specific locations and fails with firmware size changes.

This prevents driver from getting right mac addresses.

4cf1653aa9 netdevice: safe convert to netdev_priv() #part-2
We have some reasons to kill netdev->priv:
1. netdev->priv is equal to netdev_priv().
2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
   netdev_priv() is more flexible than netdev->priv.
But we cann't kill netdev->priv, because so many drivers reference to it
directly.

This patch is a safe convert for netdev->priv to netdev_priv(netdev).
Since all of the netdev->priv is only for read.
But it is too big to be sent in one mail.
I split it to 4 parts and make every part smaller than 100,000 bytes,
which is max size allowed by vger.
