From bf59878630a4fc5e74e2a9f7f12eee1a3b994fdc Mon Sep 17 00:00:00 2001 From: Kishore Padmanabha Date: Tue, 16 Nov 2021 18:34:36 +0530 Subject: [PATCH] net/bnxt: fix multi adapter 1. removed the global flag for TruFlow global config initialization. 2. Modified the TruFlow context lock to be a global lock instead of per context lock. 3. The ULP context list is modified to check on the ULP configuration data so alarm handlers can operate on the correct ULP context. These changes help in support of multiple network cards using single DPDK application.
