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 3rd patch, add a command "add_more_mac_addr port_id base_mac_addr count"
to add more than one MAC address one time.
This command can simplify the test for the first patch.
Normally a MAC address may fails to be added only after many MAC
addresses have been added.
Without this command, a tester may only trigger failed MAC address
by running many times of testpmd command 'mac_addr add' .

Changes
v3:
  1. Change return value for some specific NIC according to feedbacks
     from the community;
  2. Add ABI change in release note;
  3. Add more detailed commit message.

v2:
  fix warnings and erros from check-git-log.sh and checkpatch.pl

Wei Dai (3):
  ethdev: fix adding invalid MAC addr
  doc: change type of return value of adding MAC addr
  app/testpmd: add a command to add many MAC addrs

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.

Add following lines in section of API change in release note.

If a MAC address fails to be added without this change, it is still stored
and may be regarded as a valid one. This may lead to errors in application.
The type of return value of eth_mac_addr_add_t in rte_ethdev.h is changed.
Any specific NIC also follows this change.

This patch is added to introduce a testpmd command which
is used to add more than one MAC addresses one time.
This command can simplify the test for the change where
the type of return value of adding MAC address.
Normally a MAC address may fails to be added only after
many MAC addresses have been added.
Without this command, a tester may only trigger failed
MAC address by running many times of testpmd command
'mac_addr add' .

In the whole file, function prototypes does not provide variable names,

Same point about the indentation, the second line should be aligned with

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 3rd patch, add a command "add_more_mac_addr port_id base_mac_addr count"
to add more than one MAC address one time.
This command can simplify the test for the first patch.
Normally a MAC address may fails to be added only after many MAC
addresses have been added.
Without this command, a tester may only trigger failed MAC address
by running many times of testpmd command 'mac_addr add' .

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.

Add following lines in section of API change in release note.

If a MAC address fails to be added without this change, it is still stored
and may be regarded as a valid one. This may lead to errors in application.
The type of return value of eth_mac_addr_add_t in rte_ethdev.h is changed.
Any specific NIC also follows this change.

This patch is added to introduce a testpmd command which
is used to add more than one MAC addresses one time.
This command can simplify the test for the change where
the type of return value of adding MAC address.
Normally a MAC address may fails to be added only after
many MAC addresses have been added.
Without this command, a tester may only trigger failed
MAC address by running many times of testpmd command
'mac_addr add' .

Please, could you rebase and add changes to newly introduced drivers?

NACK here. Normally we try to avoid changing base code. And I don't think the change is necessary.

If this code is not changed, the code in ethdev may get wrong return value and assume
the failed MAC addr is added.
Anyway, we can ask the base code to be revised by the associated team.

' hw->mac.ops.rar_set ' cannot be NULL. That's why I think this change is not necessary.
