It\nstores its own copies of settings i.e. RETA, RSS hash function and RSS\nkey. It’s required to ensure consistency.\n\n1) RSS hash function set for bonding device is maximal set of RSS hash\nfunctions supported by all bonded devices. That mean, to have RSS support\nfor bonding, all slaves should be RSS-capable.\n\n2) RSS key is propagated over the slaves \"as is\".\n\n3) RETA for bonding is an internal table managed by bonding API, and is\nused as a pattern to set up slaves. Its size is GCD of all RETA sizes, so\nit can be easily used as a pattern providing expected behavior, even if\nslaves RETA sizes are different.\n\nSigned-off-by: Tomasz Kulasek
