Subject: [PATCH net-next 4/9] ionic: add generic filter search
Date: Sat, 9 Oct 2021 11:45:18 -0700 [thread overview]
Message-ID: <20211009184523.73154-5-snelson@pensando.io> (raw)
In-Reply-To: <20211009184523.73154-1-snelson@pensando.io>
In preparation for enhancing vlan filter management,
add a filter search routine that can figure out for
itself which type of filter search is needed.
