From b4938fad44912967636b96990ddba01ef6bc3064 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 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.
