From 7db20ecd1d9700e2c240dee505162eb56ab55b5b Mon Sep 17 00:00:00 2001 From: "Hiatt, Don" Date: Thu, 8 Jun 2017 13:37:49 -0400 Subject: IB/core: Change wc.slid from 16 to 32 bits slid field in struct ib_wc is increased to 32 bits. This enables core components to use larger LIDs if needed. The user ABI is unchanged and return 16 bit values when queried.
