Subject: [PATCH net-next 5/6] be2net: use SET/GET_MAC_LIST for SH-R

On SH-R and Lancer-R, GET_MAC_LIST cmd is better supported
(instead of NTWK_MAC_QUERY cmd) to query provisioned MAC addresses.
Similiarly, (on SH-R and Lancer-R) SET_MAC_LIST must be used by the PF to
provision a permanent MAC addresses to the VF.
