Subject: [PATCH] net/qede: fix default MAC address handling

[ upstream commit 49d8b54e867982d0ee55d0706d9b7cec73492542 ]

- 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.

Fixes: 2ea6f76aff40 ("qede: add core driver")
