[yomnes0]

Partial fix for bug #2697. Peer filter config should now correctly be interpreted even on big endian systems

Some weird failure on Travis, Linux runner BUILD_TYPE=Debug BUILD_OPTS='-DENABLE_LOGGING=OFF -DUSE_ENCLIB=mbedtls -DENABLE_MONOTONIC_CLOCK=ON -DENABLE_BONDING=ON -DCMAKE_CXX_FLAGS="-Werror"'.
Restarting.

Can ItoHLA just replace the above memcpy to not copy twice?

That seems to work as well, this can be done for connector's requested SID and congestion-control type as well. I'll include those changes in my next PR
