[PATCH bpf-next 6/7] bpf: selftests: Support custom type and proto for client sockets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Extend connect_to_fd_opts() to take optional type and protocol
parameters for the client socket. These parameters are useful when
opening a raw socket to send IP fragments.
