From 6644f49e7b71e13bcc5498d9fea8862c5ce96388 Mon Sep 17 00:00:00 2001 From: Giovanni Cabiddu Date: Fri, 13 Nov 2020 16:46:42 +0000 Subject: [PATCH] crypto: qat - add hook to initialize vector routing table Add an hook to initialize the vector routing table with the default values before MSIx is enabled. The new function set_msix_rttable() is called only if present in the struct adf_hw_device_data of the device. This is to allow for QAT devices that do not support that functionality.
