I get a compiler warning:
../TESTS/test-ovn-dhcp.c:220:28: error: cast from 'const char *' to
'uint32_t *' (aka 'unsigned int *') increases required alignment from 1 to 4
[-Werror,-Wcast-align]
for this:
uint32_t cookie = *(uint32_t *)footer;
Probably you should use get_unaligned_be32(), also ovs_be32 since as
sparse says:
../tests/test-ovn-dhcp.c:221:28: warning: restricted ovs_be32 degrades
to integer
This otherwise seems pretty straightforward once patch 1 is ready.
Sweet!
Thanks,
Ben.
