Subject: net/ice: initialize and update RSS based on user config
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4717a12cfaf14e4c20dc593b9e0fc5fc1b62b00f;p=dpdk.git

net/ice: initialize and update RSS based on user config

Initialize and update RSS configure based on user request
(rte_eth_rss_conf) from dev_configure and .rss_hash_update ops.
All previous default configure has been removed.
