>
>- In qede_mac_addr_set(), in order to configure default MAC address we
>first delete the existing MAC address before trying to add new one. During
>init time, there is no MAC filter to begin with, so trying to remove a
>non-existing MAC address causes a firmware exception. This can be
>prevented
>by internally calling qede_mac_addr_add() which has the checks in place to
>delete a MAC address only if it was added before.
>
>- Remove setting of the default MAC address from within
>qede_dev_configure() since rte_eth_dev_start() calls mac_addr_set()
>anyway.

Hi Yuanhan,
Sure, there are no objections to push  it to dpdk-stable.
Thanks.
