Subject: [net-next v2 09/14] ice: write register with correct offset
Date: Wed,  6 Nov 2019 11:37:51 -0800	[thread overview]
Message-ID: <20191106193756.23819-10-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20191106193756.23819-1-jeffrey.t.kirsher@intel.com>

From: Mitch Williams <mitch.a.williams@intel.com>

The VF_MBX_ARQLEN register array is per-PF, not global, so we should not
use the absolute VF ID as an index. Instead, use the per-PF VF ID.

This fixes an issue with VFs on PFs other than 0 not seeing reset.
