mlx4_core: Reduce number of PD bits to 17
When SRIOV is enabled on the chip (at FW burning time), the HCA uses only 17 bits for the PD. The remaining 7 high-order bits are ignored. Change the allocator to return only 17 bits for the PD. The MSB 7 bits will be used to encode the slave number for consistency checking later on in the resource tracker. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
