be2net: Support for configurable RSS hash key
This be2net patch implements the get/set_rxfh() ethtool hooks.
RSS_CONFIG device command is invoked to set hashkey and indirection table.
It also uses an initial random value for RSS hash key instead of a
hard-coded value as hard-coded values for a hash-key are usually
considered a security risk.
