To support TOEPLITZ hash for RSS, DPDK target has introduced a new instruction called "rss"
This instruction is similar to the already supported "hash" instruction but takes the rss type object instead of the hash algorithm.

The signature of hash extern remains the same. The algorithm should be specified as TOEPLITZ

Existing instruction: hash <hash_algo_name> dst srcfirst srclast
New instruction : rss <hash_object_name> dst srcfirst srclast
