selftests/net: timestamping: Fix bind_phc check
[ Upstream commit 678dfd5280341d877ca646499bfdc82a3d8b4356 ]
timestamping checks socket options during initialisation. For the field
bind_phc of the socket option SO_TIMESTAMPING it expects the value -1 if
PHC is not bound. Actually the value of bind_phc is 0 if PHC is not
bound. This results in the following output:
SIOCSHWTSTAMP: tx_type 0 requested, got 0; rx_filter 0 requested, got 0
SO_TIMESTAMP 0
SO_TIMESTAMPNS 0
SO_TIMESTAMPING flags 0, bind phc 0
not expected, flags 0, bind phc -1
This is fixed by setting default value and expected value of bind_phc to
0.
