ixgbe: Fix incorrect bitwise operations of PTP Rx timestamp flags
Rx timestamp does not work on 82599 and X540 because bitwise operation of RX_HWTSTAMP flags is incorrect and ixgbe_ptp_rx_hwtstamp() is never called. This patch fixes it to enable Rx timestamp on 82599 and X540. Without this fix: ptp4l[278.730]: selected /dev/ptp8 as PTP clock ptp4l[278.733]: port 1: INITIALIZING to LISTENING on INITIALIZE ptp4l[278.733]: port 0: INITIALIZING to LISTENING on INITIALIZE ptp4l[278.834]: port 1: received SYNC without timestamp ptp4l[278.835]: port 1: new foreign master 1c3947.fffe.60f9cc-1 ptp4l[279.834]: port 1: received SYNC without timestamp ptp4l[280.834]: port 1: received SYNC without timestamp ptp4l[281.834]: port 1: received SYNC without timestamp ptp4l[282.834]: port 1: received SYNC without timestamp ptp4l[282.835]: selected best master clock 1c3947.fffe.60f9cc ptp4l[282.835]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE ptp4l[283.834]: port 1: received SYNC without timestamp With this fix: ptp4l[239.154]: selected /dev/ptp8 as PTP clock ptp4l[239.157]: port 1: INITIALIZING to LISTENING on INITIALIZE ptp4l[239.157]: port 0: INITIALIZING to LISTENING on INITIALIZE ptp4l[240.989]: port 1: new foreign master 1c3947.fffe.60f9cc-1 ptp4l[244.989]: selected best master clock 1c3947.fffe.60f9cc ptp4l[244.989]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE ptp4l[246.977]: master offset -899583339542096 s0 freq +0 path delay 16222 ptp4l[247.977]: master offset -899583339617265 s1 freq -75169 path delay 16177 ptp4l[248.977]: master offset -130 s2 freq -75299 path delay 16177 ptp4l[248.977]: port 1: UNCALIBRATED to SLAVE on MASTER_CLOCK_SELECTED ptp4l[249.977]: master offset -9 s2 freq -75217 path delay 16177 ptp4l[250.977]: master offset 88 s2 freq -75123 path delay 16132 Fixes: a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x devices") Signed-off-by: Yusuke Suzuki <yus-suzuki@uf.jp.nec.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
