Test testTetherUdpV4AfterR only verify bpf in precise kernel range
Use three-part kernel version numbers to check which device
needs to verify BPF offload. Only check major and minor number
is not enough. Ex: mixed build T + R may have an unsupported kernel
version 4.19.160 (require 4.19.176+). Now check the subminor
number as well.
For UDPv4 support, kernel require 4.14.222+ 4.19.176+ 5.4.98+, 5.8.0+
Test: atest EthernetTetheringTest (raven @ internal master build)
Test: cts test (bramble @ T + R mixed build)
> run cts-on-gsi -m CtsTetheringTest -t android.net.EthernetTetheringTest#testTetherUdpV4AfterR
