[dpdk-stable] [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.

[dpdk-stable] [PATCH 2/2] net/mrvl: allow adding ether addr before port init

[Tomasz Duszynski]

Since DPDK restores ether address configuration after device
is started it is safe to add ether address to uninitialized port (ppio).
