Date: Thu, 6 Jan 2022 10:30:09 -0800 From: Tony Nguyen <anthony.l.nguyen@...el.com> To: davem@...emloft.net, kuba@...nel.org Cc: Victor Raj <victor.raj@...el.com>, netdev@...r.kernel.org, anthony.l.nguyen@...el.com, Wojciech Drewek <wojciech.drewek@...el.com>, Sandeep Penigalapati <sandeep.penigalapati@...el.com> Subject: [PATCH net-next 1/5] ice: replay advanced rules after reset From: Victor Raj <victor.raj@...el.com> ice_replay_vsi_adv_rule will replay advanced rules for a given VSI. Exit this function when list of rules for given recipe is empty. Do not add rule when given vsi_handle does not match vsi_handle from the rule info. Use ICE_MAX_NUM_RECIPES instead of ICE_SW_LKUP_LAST in order to find advanced rules as well.
