When converting the Renesas network drivers to use flags from enum
hwtstamp_rx_filters to control when to timestamp packages instead of a
driver specific schema with bit-wise flags an error was made.
The bit-wise driver specific flags correct logic to set get_ts was:
q: RAVB_BE + tstamp_rx_ctrl: 0 => 0
q: RAVB_NC + tstamp_rx_ctrl: 0 => 0
q: RAVB_BE + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_V2_L2_EVENT => 0
q: RAVB_NC + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_V2_L2_EVENT => 1
q: RAVB_BE + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_ALL => 1
q: RAVB_NC + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_ALL => 1
The converted logic to use enum flags mapped tstamp_rx_ctrl as
0 to HWTSTAMP_FILTER_NONE
RAVB_RXTSTAMP_TYPE_V2_L2_EVENT to HWTSTAMP_FILTER_PTP_V2_L2_EVENT
RAVB_RXTSTAMP_TYPE_ALL to HWTSTAMP_FILTER_ALL
But the logic was incorrectly changed to:
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_NONE => 1 (error)
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_NONE => 0
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_PTP_V2_L2_EVENT => 0
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_PTP_V2_L2_EVENT => 1
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_ALL => 1
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_ALL => 0 (error)
This change restores the converted flag check to the correct logic of
the bit-wise driver specific flags.
