Subject: [dpdk-dev] [PATCH] net/bnxt: disable receive end-of-packet padding
Date: Thu, 3 Dec 2020 09:16:21 -0500 [thread overview]
Message-ID: <20201203141621.160040-1-lance.richardson@broadcom.com> (raw)
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.
Fixes: f4253e97e7b0 ("net/bnxt: set padding flags in Rx descriptor")
