It will be pushed if I get no objections before 02/06/21. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/cpaelzer/dpdk-stable-queue This queued commit can be viewed at: https://github.com/cpaelzer/dpdk-stable-queue/commit/05648cbaa45ea55fc160590d429f23f859370cfb Thanks. Christian Ehrhardt --- >From 05648cbaa45ea55fc160590d429f23f859370cfb Mon Sep 17 00:00:00 2001 From: Lance Richardson Date: Thu, 3 Dec 2020 09:16:21 -0500 Subject: [PATCH] net/bnxt: disable end of packet padding for Rx [ upstream commit b4938fad44912967636b96990ddba01ef6bc3064 ] Testing has shown that the packet forwarding rate for packet sizes that are not a multiple of the cache line size is reduced when the DMA size is padded to a multiple of the cache line size. Improve performance for these packet sizes by disabling EOP padding.
