Current enic code only supports ASSOCIATE and DISASSOCIATE port profile
operations. This patch adds enic support for port profile
PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable
of handling port profile requests done in two steps namely PREASSOCIATE_RR
and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly
from its use as an optimization during VM migration ie, to do resource
reservation on destination host before resources on source host are released.
PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE,
8021qbh will also need to support VDP commands.
In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation
this patch also does the below:
- Introduces handlers for PORT_REQUEST operations
- Moves most of the port profile handling code to new files enic_pp.[ch]
- Uses new fw devcmds for port profile operations

Add enic ndo_{set|get}_vf_port ops to support setting/getting
port-profile for enic dynamic devices. Enic dynamic devices are just like
normal enic eth devices except dynamic enics require an extra configuration
step to assign a port-profile identifier to the interface before the
interface is useable. Once a port-profile is assigned, link comes up on the
interface and is ready for I/O. The port-profile is used to configure the
network port assigned to the interface. The network port configuration
includes VLAN membership, QoS policies, and port security settings typical
of a data center network.
A dynamic enic initially has a zero-mac address. Before a port-profile is
assigned, a valid non-zero unicast mac address should be assign to the
dynamic enic interface.
