Thanks for taking time to review this patch. The default MAC address is read
from hardware
and copied to dev->data->mac_addrs in eth_fm10k_dev_init, but the
fm10k_MAC_filter_set
previously was called in fm10k_dev_start, which caused this issue.

The error message is "MAC address number not match", it is only an error
message, because
fm10k_dev_start will eventually be called when default_vid was ready, and
MAC/VLAN table
will be updated correctly. default_vid is necessary for fm10k to function
correctly.

fm10k_MAC_filter_set is moved from eth_fm10k_dev_init to eth_fm10k_dev_init,
aligned with
the place where the default MAC address is actually read and copied.
