Multi host Mellanox cards require MAC affinity to be set before receiving any config commands. All config commands should also have unicast address for source address in command header. Adding GMA and SMAF(Set Mac Affinity) for Mellanox card and call these in channel probe state machine if it is defined in device tree.

After receiving device mac address from device, send this as a source address for further commands instead of broadcast address. This will help in multi host NIC cards. Signed-off-by: Vijay Khemka <vijaykhemka@fb.com> Signed-off-by: David S. Miller <davem@davemloft.net>
gma_flag was set at the time of GMA command request but it should only be set after getting successful response. Movinng this flag setting in GMA response handler. This flag is used mainly for not repeating GMA command once received MAC address.

Disabling multicast filtering from NCSI if it is supported. As it should not filter any multicast packets. In current code, multicast filter is enabled and with an exception of optional field supported by device are disabled filtering. Mainly I see if goal is to disable filtering for IPV6 packets then let it disabled for every other types as well. As we are seeing issues with LLDP not working with this enabled filtering. And there are other issues with IPV6. By Disabling this multicast completely, it is working for both IPV6 as well as LLDP.

This patch adds handlers for PLDM over NC-SI command response. This enables NC-SI driver recognizes the packet type so the responses don't get dropped as unknown packet type. PLDM over NC-SI are not handled in kernel driver for now, but can be passed back to user space via Netlink for further handling. Signed-off-by: Ben Wei <benwei@fb.com> Signed-off-by: David S.

The request coming from Netlink should use the OEM generic handler. The standard command handler expects payload in bytes/words/dwords but the actual payload is stored in data if the request is coming from Netlink.
