From c92f053d4e2d3a2f42d1ad97fc596e8b3b86346a Mon Sep 17 00:00:00 2001 From: Kalesh AP Date: Fri, 28 Aug 2020 10:31:11 +0530 Subject: [PATCH] net/bnxt: fix L2 filter allocation DPDK does not support RoCE and XDP. The driver should set the bit 5:4 of the flag to 1 and set bit 6 of the flag in the HWRM_CFA_L2_FILTER_ALLOC command to disable RoCE and XDP features. This change will greatly reduce the CFA resource consumption.
