Subject: [net-next 10/12] i40evf: Correctly populate rxitr_idx and txitr_idx
Date: Mon, 12 Feb 2018 12:46:47 -0800 [thread overview]
Message-ID: <20180212204649.24178-11-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20180212204649.24178-1-jeffrey.t.kirsher@intel.com>
From: Alexander Duyck <alexander.h.duyck@intel.com>
While testing code for the recent ITR changes I found that updating the Tx
ITR appeared to have no effect with everything defaulting to the Rx ITR. A
bit of digging narrowed it down the fact that we were asking the PF to
associate all causes with ITR 0 as we weren't populating the itr_idx values
for either Rx or Tx.
To correct it I have added the configuration for these values to this
patch. In addition I did some minor clean-up to just add a local pointer
for the vector map instead of dereferencing it based off of the index
repeatedly. In my opinion this makes the resultant code a bit more readable
and saves us a few characters.
