Subject[PATCH AUTOSEL 5.2 104/123] net: stmmac: tc: Do not return a fragment entry
Date
From: Jose Abreu <Jose.Abreu@synopsys.com>

[ Upstream commit 4a6a1385a4db5f42258a40fcd497cbfd22075968 ]

Do not try to return a fragment entry from TC list. Otherwise we may not
clean properly allocated entries.
