Thank you work working on ERSPAN support.
"sparse" says:
../lib/netdev-native-tnl.c:458:29: error: cast from 'char *' to 'ovs_be32
*' (aka 'unsigned int *') increases required alignment from 1 to 4
[-Werror,-Wcast-align]
I think that it is probably right that this is a bit risky, because OVS
cannot always ensure that packet data is 32-bit aligned. You can use
ovs_16aligned_be32 and get_16aligned_be32, or even get_unaligned_be32,
here.
