From 4cd7c9479aff33746af490fa4a5a7dee8654891a Mon Sep 17 00:00:00 2001 From: Ira Weiny Date: Sat, 6 Jun 2015 14:38:31 -0400 Subject: IB/mad: Add support for additional MAD info to/from drivers In order to support alternate sized MADs (and variable sized MADs on OPA devices) add in/out MAD size parameters to the process_mad core call. In addition, add an out_mad_pkey_index to communicate the pkey index the driver wishes the MAD stack to use when sending OPA MAD responses. The out MAD size and the out MAD PKey index are required by the MAD stack to generate responses on OPA devices. Furthermore, the in and out MAD parameters are made generic by specifying them as ib_mad_hdr rather than ib_mad. Drivers are modified as needed and are protected by BUG_ON flags if the MAD sizes passed to them is incorrect.
