Subject: [PATCH v5 bpf-next 02/17] selftests: xsk: remove struct ifaceconfigobj
Date: Tue, 30 Mar 2021 00:43:01 +0200	[thread overview]
Message-ID: <20210329224316.17793-3-maciej.fijalkowski@intel.com> (raw)
In-Reply-To: <20210329224316.17793-1-maciej.fijalkowski@intel.com>

ifaceconfigobj is not really useful, it is possible to keep the
functionality and simplify the code.
