From 56f9920a952130a7cd20952b3525bc238a87e489 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Wed, 4 Jun 2014 04:22:41 +0000 Subject: [PATCH] i40evf: resend FW request if no response Sometimes the firmware will not indicate an error but fail to pass a message between the VF and the PF driver. If this happens, just resend the request. This fixes an initialization failure if many VFs are instantiated at the same time and the VF module is autoloaded.
