Subject: [PATCH net 3/3] net: stmmac: tc: Do not return a fragment entry
Date: Tue, 6 Aug 2019 15:16:18 +0200 [thread overview]
Message-ID: <67f380701fc127022e1d5a0922725bdf1bc185f4.1565097294.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1565097294.git.joabreu@synopsys.com>
In-Reply-To: <cover.1565097294.git.joabreu@synopsys.com>
Do not try to return a fragment entry from TC list. Otherwise we may not
clean properly allocated entries.
