Date: Fri, 30 Oct 2020 03:49:10 +0200 From: Vladimir Oltean <vladimir.oltean@....com> To: netdev@...r.kernel.org Cc: andrew@...n.ch, f.fainelli@...il.com, vivien.didelot@...il.com, kuba@...nel.org, Christian Eggers <ceggers@...i.de>, Kurt Kanzenbach <kurt@...utronix.de>, Per Forlin <per.forlin@...s.com>, Oleksij Rempel <linux@...pel-privat.de> Subject: [PATCH v2 net-next 12/12] net: dsa: tag_ar9331: let DSA core deal with TX reallocation Now that we have a central TX reallocation procedure that accounts for the tagger's needed headroom in a generic way, we can remove the skb_cow_head call.
