From 468d8b462ac64659caec53eff34f02963d5f52c8 Mon Sep 17 00:00:00 2001 From: Dave Ertman Date: Tue, 15 Apr 2025 21:15:45 -0500 Subject: iidc/ice/irdma: Rename IDC header file To prepare for the IDC upgrade to support different CORE PCI drivers, rename header file from iidc.h to iidc_rdma.h since this files functionality is specifically for RDMA support. Use net/dscp.h include in irdma osdep.h and DSCP_MAX type.h, instead of iidc header and define.
