Current ethdev always stores MAC address even it fails to be added.
Other function may regard the failed MAC address valid and lead to
some errors. So There is a need to check if the addr is added
successfully or not and discard it if it fails.

In 2nd patch, add a command "add_more_mac_addr port_id base_mac_addr count"
to add more than one MAC address one time. It is also for testing this fix.

some customers find adding mac addr to VF sometimes can fail,
but it is still stored in dev->data->mac_addrs[ ]. So this
can lead to some errors that assumes the non-zero entry in
dev->data->mac_addrs[ ] is valid.

Should not it return ENOSUP instead?

You have an issue here, internal function of mlx drivers return

It should be negated before returning.

* [PATCH 1/2] ethdev: fix adding invalid mac addr
  2017-03-31 17:04 [PATCH 0/2] mac addr fail to be added shouldn't be storeid Wei Dai
@ 2017-03-31 17:04 ` Wei Dai
  0 siblings, 0 replies; 6+ messages in thread
From: Wei Dai @ 2017-03-31 17:04 UTC (permalink / raw)
  To: dev; +Cc: Wei Dai, stable

some customers find adding mac addr to VF sometimes can fail,
but it is still stored in dev->data->mac_addrs[ ]. So this
can lead to some errors that assumes the non-zero entry in
dev->data->mac_addrs[ ] is valid.

Fixes: af75078fece3 ("first public release")
Cc: stable@dpdk.org
