Subject: [PATCH 1/7] net/ixgbe: Fix ixgbe_is_sfp() to return valid result for X550EM_a devs
Date: Fri,  3 Dec 2021 17:55:10 -0500	[thread overview]
Message-ID: <20211203225516.571368-2-stephend@silicom-usa.com> (raw)
In-Reply-To: <20211203225516.571368-1-stephend@silicom-usa.com>

Currently all X500EM* MAC types fallthrough to the default case and get
reported as non-SFP regardless of media type, which isn't correct.

Fixes: 0790adeb567 ("ixgbe/base: support X550em_a device")
Cc: stable@dpdk.org
