From 0ba9a3b65c794982f4dc7fcdc8110c327359916b Mon Sep 17 00:00:00 2001 From: Kumar Sanghvi Date: Wed, 1 Nov 2017 08:52:59 +0530 Subject: [PATCH] cxgb4: save additional filter tuple field shifts in tp_params Save additional filter tuple field shifts in tp_params based on configured filter tuple fields. Also, save the combined filter tuple mask based on configured filter tuple fields. Signed-off-by: Kumar Sanghvi Signed-off-by: Rahul Lakkireddy Signed-off-by: Ganesh Goudar Signed-off-by: David S.
