bonding: fix incorrect software timestamping report
[ Upstream commit a95b031c6796bf9972da2d4b4b524a57734f3a0a ]
The __ethtool_get_ts_info function returns directly if the device has a
get_ts_info() method. For bonding with an active slave, this works correctly
as we simply return the real device's timestamping information. However,
when there is no active slave, we only check the slave's TX software
timestamp information. We still need to set the phc index and RX timestamp
information manually. Otherwise, the result will be look like:
Time stamping parameters for bond0:
Capabilities:
software-transmit
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none
This issue does not affect VLAN or MACVLAN devices, as they only have one
downlink and can directly use the downlink's timestamping information.
Fixes: b8768dc40777 ("net: ethtool: Refactor identical get_ts_info implementations.")
