From 5075314e4e4b559cc37675ad8a721a89bccd6284 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 15 Sep 2014 13:00:19 -0400 Subject: [PATCH] dsa: Split ops up, and avoid assigning tag_protocol and receive separately This change addresses several issues. First, it was possible to set tag_protocol without setting the ops pointer. To correct that I have reordered things so that rcv is now populated before we set tag_protocol. Second, it didn't make much sense to keep setting the device ops each time a new slave was registered. So by moving the receive portion out into root switch initialization that issue should be addressed. Third, I wanted to avoid sending tags if the rcv pointer was not registered so I changed the tag check to verify if the rcv function pointer is set on the root tree. If it is then we start sending DSA tagged frames. Finally I split the device ops pointer in the structures into two spots. I placed the rcv function pointer in the root switch since this makes it easiest to access from there, and I placed the xmit function pointer in the slave for the same reason.
