Subject: [dpdk-dev] [PATCH 01/12] net/bnxt: fix burst mode get for Arm
Date: Wed,  9 Sep 2020 11:52:54 -0400
Message-ID: <20200909155302.28656-2-lance.richardson@broadcom.com> (raw)
In-Reply-To: <20200909155302.28656-1-lance.richardson@broadcom.com>

Transmit and receive burst mode get operations incorrectly return
"Vector SSE" on ARM64 platforms, change to return "Vector Neon"
instead.

Fixes: 3983583414 ("net/bnxt: support NEON")
