From a6e2846cacf97d4c70c5e923325b015cfa1e9053 Mon Sep 17 00:00:00 2001 From: Sudarsana Reddy Kalluru Date: Fri, 21 Oct 2016 02:09:17 -0400 Subject: [PATCH] bnx2x: Use the correct divisor value for PHC clock readings. Time Sync (PTP) implementation uses the divisor/shift value for converting the clock ticks to nanoseconds. Driver currently defines shift value as 1, this results in the nanoseconds value to be calculated as half the actual value. Hence the user application fails to synchronize the device clock value with the PTP master device clock. Need to use the 'shift' value of 0.
