From 17850f2b0b4b806e47cc44df94186bfc2cdd490b Mon Sep 17 00:00:00 2001 From: Mustafa Ismail Date: Fri, 25 Feb 2022 10:32:11 -0600 Subject: [PATCH] RDMA/irdma: Remove incorrect masking of PD The PD id is masked with 0x7fff, while PD can be 18 bits for GEN2 HW. Remove the masking as it should not be needed and can cause incorrect PD id to be used.
