WoL on MCX4121A-ACAT

[Jamy]

I am trying to setup Mellanox cards to wake on lan, so that I can wakeup my backup TrueNAS scale box for nightly replication. Does anyone know a reliable way to determine if Wake On Lan is supported on Mellanox cards? I have MCX4121A-ACAT and MCX455-ECAT cards and so far the information I've found on determining support for WoL is inconsistent to say the least.

Thanks

NVIDIA model firmware does not support WOL, but you can find it on other OEM cards, such as Huawei SP382, QNAP onboard lom, etc...
You can run flint.bat -i fw.bin dc to check if there are these configurations in the firmware config.
If there are, WOL will be supported.

nv_config.fw_config.port[0].keep_link_up.keep_eth_link_up = 0x1
nv_config.fw_config.port[1].keep_link_up.keep_eth_link_up = 0x1
nv_config.fw_config.port[0].keep_link_up.keep_link_up_on_standby = 0x1
nv_config.fw_config.port[1].keep_link_up.keep_link_up_on_standby = 0x1
nv_config.fw_config.port[0].keep_link_up.keep_link_up_on_boot = 0x1
nv_config.fw_config.port[1].keep_link_up.keep_link_up_on_boot = 0x1
host_management.wol_cap.magic_packet = 0x11
nv_config.fw_config.host[0].port[0].wol.en_wol_magic = 1
nv_config.fw_config.host[0].port[1].wol.en_wol_magic = 1

Are those strings to search for using the standard mellanox tools?

As long as you install any version of the mft tool, there will be a flint command

From what I can find, only the OCP versions of the NIC's support WoL. It seems Broadcom is the same also. I'm also looking at SolarFlare (AMD) and Marvell to see if any of their cards support WoL.
