Subject: [PATCH v6 5/5] net: Do not fill legacy info_str for backends
Date: Tue,  2 Mar 2021 21:02:05 +0300	[thread overview]
Message-ID: <20210302180205.5009-6-lekiravi@yandex-team.ru> (raw)
In-Reply-To: <20210302180205.5009-1-lekiravi@yandex-team.ru>

As we use QAPI NetClientState->stored_config to store and get information
about backend network devices, we can drop fill of legacy field info_str
for them.

We still use info_str field for NIC and hubports, so we can not completely
remove it.
