If anyone has any objections, please let me know. ------------------ From: Victor Skvortsov [ Upstream commit 60c58d72afb81d2dc3f52f638eff5197511ac114 ] The SRIOV PF/VF Data exchange is extended by 64KB for VF RAS Telemetry data. Add Host RAS Telemetry enable capabilities bitfields. Add a new VF msg REQ_RAS_ERROR_COUNT, the host response data will be populated in the RAS Telemetry region.
