From b5d31f29402791d9d4fadddb2f2d507fefd95939 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Thu, 30 Nov 2017 18:21:17 -0600 Subject: [PATCH] net: ethernet: ti: ale: optimize ale entry mask bits configuartion The ale->params.ale_ports parameter can be used to deriver values for all ale entry mask bits: port_mask_bits, port_mask_bits, port_num_bits. Hence, calculate above values and drop all hardcoded values. For port_num_bits calcualtion use order_base_2() API. Signed-off-by: Grygorii Strashko Signed-off-by: David S.
