The rp_filter test in fib_tests.sh installs tc filters using the "basic" classifier but does not verify the corresponding kernel module (cls_basic) is available. On kernels built without CONFIG_NET_CLS_BASIC, the tc command fails and the rp_filter test is reported as a failure. Add a check for the presence of the cls_basic module and skip the rp_filter test when the classifier is not available.
