-- ERROR sending ciphering mode command: rc=-95 +- ERROR sending ciphering mode command: rc=-122
i.e. a mismatching rc gets returned. It's not an error with any practical effect.
Aha, could it simply be that the errno are defined differently on this platform? It should be -95 == -ENOTSUP, while we get -122.
Correct guess!
In /usr/include/mipsel-linux-gnu/asm/errno.h, EOPNOTSUPP is set to 122. While in /usr/include/asm-generic/errno.h (used on amd64), it is set to 95
