[net-next 06/15] i40e: remove workaround for Open Firmware MAC address

From: Jacob Keller Since commit b499ffb0a22c ("i40e: Look up MAC address in Open Firmware or IDPROM"), we've had support for obtaining the MAC address form Open Firmware or IDPROM. This code relied on sending the Open Firmware address directly to the device firmware

[net-next 05/15] i40e: separate hw_features from runtime changing flags

From: Jacob Keller The number of flags found in pf->flags has grown quite large, and there are a lot of different types of flags. Most of the flags are simply hardware features which are enabled on some firmware or some MAC types. Other flags are dynamic run-time flags
