    enic: Add support for PORT_REQUEST_PREASSOCIATE_RR · b3abfbd2
    Roopa Prabhu authored
    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
