From 5c305e218f15552d828e10293d19d9a06c4747f4 Mon Sep 17 00:00:00 2001 From: Peng Zhang Date: Wed, 15 Jun 2022 12:14:17 +0200 Subject: [PATCH] net/nfp: fix initialization When the testpmd start-up, it will check MTU range, if MTU > flubfsz, it will lead testpmd start fail. Because the hw->flbufsz doesn't have the initialized value, so it will lead the bug.
