[dpdk-stable] [PATCH v3 1/3] ethdev: fix adding invalid MAC addr

[dpdk-stable] [PATCH v3 1/3] ethdev: fix adding invalid MAC addr

[Wei Dai]

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")

Please keep the coding style consistency among the file, this last
snippet should be:

        re = priv_mac_addr_add(priv, index,
                               (const uint8_t (*)[ETHER_ADDR_LEN])
                               mac_addr->addr_bytes);

In the whole file, function prototypes does not provide variable names,
please keep it as is.

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

[dpdk-stable] [PATCH v4 1/3] ethdev: fix adding invalid MAC addr

[Wei Dai]

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
