From 7738613e7cb419179545910744b1777d87edac5c Mon Sep 17 00:00:00 2001 From: Ira Weiny Date: Wed, 13 May 2015 20:02:58 -0400 Subject: IB/core: Add per port immutable struct to ib_device As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data.
