From e9a705c3a426acd2321274fb1e5004d7940094f8 Mon Sep 17 00:00:00 2001 From: Somnath Kotur Date: Sun, 25 Oct 2020 20:56:08 -0700 Subject: [PATCH] net/bnxt: modify HWRM command to create reps Use cfa pair alloc for configuring reps. Instead of cfa_vfr_alloc for Wh+ and cfa_pair_alloc for Stingray, converge to cfa_pair_alloc/free for both devices. Set the command request structure bits accordingly. As part of this, remove the old cfa_vfr_alloc cmd definitions as FW has deprecated support for those commands.
