[PATCH] selftests/tls: Fix tls selftests dependency to correct algorithm

by Tianjia Zhang

Commit d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") moves the SM3 and SM4 stand-alone library and the algorithm implementation for the Crypto API into the same directory, and the corresponding relationship of Kconfig is modified, CONFIG_CRYPTO_SM3/4 corresponds to the stand-alone library of SM3/4, and CONFIG_CRYPTO_SM3/4_GENERIC corresponds to the algorithm implementation for the Crypto API. Therefore, it is necessary for this module to depend on the correct algorithm. Fixes: d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") Cc: Jason A.

[PATCH v4 net-next 8/8] selftests: Add a basic HSR test.

by Sebastian Andrzej Siewior

This test adds a basic HSRv0 network with 3 nodes. In its current shape it sends and forwards packets, announcements and so merges nodes based on MAC A/B information. It is able to detect duplicate packets and packetloss should any occur.
