    [SCSI] qla2xxx: Rework MSI-X handlers. · 87f27015
    Andrew Vasquez authored
    Since MSI-X vectors do not require a clearing "handshake" from
    the system perspective, and the registered handler will not be
    called more than once for one occurrence of receipt of a vector,
    there is no requirement to flush the risc register write clearing
    the interrupt condition in the risc. Also, since the msi-x
    registered handlers are optimised for a particular vector, it is
    preferable to handle the one vector received per invocation of
    the handler.
