Currently, the test result does not differentiate between the cases when
either one of the address families are configured or if both the address
families are configured. Ideally, the result should report if a
particular case was skipped.
./drivers/net/ping.py
TAP version 13
1..7
ok 1 ping.test_default_v4 # SKIP Test requires IPv4 connectivity
ok 2 ping.test_default_v6
ok 3 ping.test_xdp_generic_sb
ok 4 ping.test_xdp_generic_mb
ok 5 ping.test_xdp_native_sb
ok 6 ping.test_xdp_native_mb
ok 7 ping.test_xdp_offload # SKIP device does not support offloaded XDP
Totals: pass:5 fail:0 xfail:0 xpass:0 skip:2 error:0
Fixes: 75cc19c8ff ("selftests: drv-net: add xdp cases for ping.py")
