From f5311ac109b21c9b47118655a5b6d887bcc686f8 Mon Sep 17 00:00:00 2001 From: Jack Morgenstein Date: Tue, 13 Dec 2011 04:12:13 +0000 Subject: 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 Signed-off-by: David S.
