Since the only crypto functions used by the mptcp code are the SHA-256 library functions and crypto_memneq(), select only the options needed for those: CRYPTO_LIB_SHA256 and CRYPTO_LIB_UTILS. Previously, CRYPTO was selected instead of CRYPTO_LIB_UTILS. That does pull in CRYPTO_LIB_UTILS as well, but it's unnecessarily broad. Years ago, the CRYPTO_LIB_* options were visible only when CRYPTO. That may be another reason why CRYPTO is selected here. However, that was fixed years ago, and the libraries can now be selected directly.

Multipath TCP (MPTCP) connections send and receive data over multiple

|
subflows in order to utilize multiple network paths. Each subflow

uses the TCP protocol, and TCP options carry header information for
