net/ncsi: BMC gets incorrect ipv6 link-local address

[Tao Ren]

Hi,

I enabled NCSI_OEM_CMD_GET_MAC on my Yamp BMC to update BMC's MAC address while bringing up eth0, but I notice BMC's ipv6-link-local address may be derived from the old MAC address, which leads to DHCP failure when DHCPv6 server assigns IP based on ipv6 link local address.

Currently I workaround the issue by restarting BMC's eth0 interface (which refreshes ipv6 link local address based on the new MAC), but I'm looking for an "official" fix. For example, shall we notify network layer when BMC MAC address is updated?


Thanks,

Tao
