[dpdk-dev] [PATCH 1/2] net/mrvl: allow changing MTU before port init

[Tomasz Duszynski]

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.

Fixes: c0511a8f741f ("net/mrvl: check if ppio is initialized")
