bnxt_en: Reduce maximum ring pages if page size is 64K.
The chip supports 4K/8K/64K page sizes for the rings and we try to match it to the CPU PAGE_SIZE. The current page size limits for the rings are based on 4K/8K page size. If the page size is 64K, these limits are too large. Reduce them appropriately. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
