From 1f0cf89b09305743fca5898660a7be83aab38a74 Mon Sep 17 00:00:00 2001 From: Ilan Tayari Date: Wed, 30 May 2018 10:59:50 -0700 Subject: net/mlx5: Add FPGA QP error event The FPGA queue pair (QP) event fires whenever a QP on the FPGA transitions to the error state. At this stage, this event is unrecoverable, it may become recoverable in the future. Signed-off-by: Ilan Tayari Signed-off-by: Adi Nissim Signed-off-by: Saeed Mahameed Signed-off-by: David S.
