[strongSwan] syslog Error "00[LIB] opening AF_ALG socket failed: Address family not supported by protocol"

It seems that your kernel does not support the AF_ALG crypto API. On
such a kernel, it makes no sense to enable the af-alg plugin, but
instead use other/default crypto modules. Try to ./configure strongSwan
without --enable-af-alg.
