Tests for lwIP's sock_udp port
This tests the
sock_udp port of lwIP. There is no network device needed since
a virtual device is
provided at the backend.
These tests test both IPv4 and IPv6 capabilities. They can be activated by
LWIP_IPV6 environment variables to a non-zero value.
IPv6 is activated by default:
make all test # or LWIP_IPV6=1 make all test
To just test IPv4 set the
LWIP_IPV4 to a non-zero value (IPv6 will be
LWIP_IPV4=1 make all test
To test both set the
LWIP_IPV6 to a non-zero value:
LWIP_IPV4=1 LWIP_IPV6=1 make all test
Since lwIP uses a lot of macro magic to activate/deactivate these capabilities it is advisable to test all three configurations individually (just IPv4, just IPv6, IPv4/IPv6 dual stack mode).
