> rx_mini_pending was set to an incorrect value. This was causing EINVAL to
> always be returned to 'ethtool -G'. The driver does not support mini or
> jumbo rings so the respective settings should be zero.
> 
> Also, change the valid range of the number of descriptors in the rings to
> make the code simpler and easier for users to understand (this removes the
> valid settings of 8 and 16). Add a system log message indicating when the
> number is rounded-up from what the user specifies with the 'ethtool -G'
> command (i.e. when it is not a multiple of 32), and update the log message
> when a user-provided value is out of range to also indicate the stride.
