Subject: [net-next 21/21] ixgbe: Add PF support for VF promiscuous mode
From: Don Skidmore <donald.c.skidmore@...el.com>
This patch extends the xcast mailbox message to include support for
unicast promiscuous mode. To allow a VF to enter this mode the PF
must be in promiscuous mode.
A later patch will add the support needed in the VF driver (ixgbevf)
