[Intel-wired-lan] [PATCH net-next 0/3] i40e: Add software controlled DCB feature

DCB feature was supported by Firmware LLDP agent only.
If Firmware LLDP agent is enabled it receives DCB related TLVs,
then it configures hardware accordingly.

Allow the OS to take control of handling LLDP frames related
to DCB functionality.

After disabling the Firmware LLDP agent (private flag:
disable-fw-lldp : on), the driver configures DCB with default
values (only one Traffic Class). At the same time, it
allows the OS (software based LLDP agent - userspace application
i.e. lldpad) to receive DCB TLVs and set desired DCB config
through DCB related netlink callbacks.
