If anyone has any objections, please let me know. ------------------ From: Chenguang Zhao [ Upstream commit fe0c002928c6749b7f4a726f6f600f6dd70280ea ] rss_indir_user and rss_hkey_user are allocated and filled in __set_rss_rxfh() when the user configures RSS via ethtool, but nothing ever reads them. hinic_get_rxfh() fetches the state from the device, and the hardware is programmed from the original indir/key arguments. These buffers only leaked on driver unload. Drop the unused allocations, memcpys, and struct fields.
