From a5dd308778a4e05e7b0b927cf18b89d1ebbff59c Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 6 Dec 2018 11:36:04 +0100 Subject: net: dsa: Add overhead to tag protocol ops. Each DSA tag protocol needs to add additional headers to the Ethernet frame in order to direct it towards a specific switch egress port. It must also remove the head from a frame received from a switch. Indicate the maximum size of these headers in the tag protocol ops structure, so the core can take these overheads into account.
