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
