Subject: [PATCH v2] i40e: fix i40evf_add_mac_addr to permit multicast
addresses

From: David Harton <redacted>

The i40e maintains a single MAC filter table for both unicast and multicast
addresses.  The i40e_validate_mac_addr function was preventing multicast
addresses from being added to the table via i40evf_add_mac_addr.  Fixed
the issue by adjusting the check in i40evf_add_mac_addr.

Fixes: 4861cde46116 ("i40e: new poll mode driver")
Fixes: 97ac72aa71a9 ("i40e: support setting VF MAC address")

v2
* Removed multicast check in i40evf_add_mac_addr.

v1
* Removed multicast check in i40e_validate_mac_addr.

Thanks for the patch, there's some mistake with my last comment.

According to the comment of is_zero_ether_addr function, return value should be 0 or 1.
So you should use if (!is_zero_ether_addr(addr))  here.
