Subject: [PATCH intel-net v2 4/6] igb: add correct exception tracing for XDP
Date: Mon, 10 May 2021 11:38:52 +0200 [thread overview]
Message-ID: <20210510093854.31652-5-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20210510093854.31652-1-magnus.karlsson@gmail.com>
From: Magnus Karlsson <magnus.karlsson@intel.com>
Add missing exception tracing to XDP when a number of different
errors can occur. The support was only partial. Several errors
where not logged which would confuse the user quite a lot not
knowing where and why the packets disappeared.
Fixes: 9cbc948b5a20 ("igb: add XDP support")
Reported-by: Jesper Dangaard Brouer <brouer@redhat.com>
