[dpdk-dev] [PATCH 5/6] net/bnxt: fix L2 filter alloc

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

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.

Fixes: f92735db1e4c ("net/bnxt: add L2 filter alloc/init/free")
