From 59c796c889c7b1a001b1e3354750baa2ca9bdba9 Mon Sep 17 00:00:00 2001 From: Tomasz Duszynski Date: Thu, 18 Jan 2018 11:57:36 +0100 Subject: [PATCH] net/mrvl: allow changing MTU before port init DPDK updates MTU once mtu_set() callback returns success. Since PMD changes port's MTU to dev->mtu every time device is started it is safe to call mtu_set() before MUSDK ppio was initialized.
