[Qemu-devel] [PATCH v10 0/8] the reset of msix_init series

[Cao jin]

v10 changelog:
1. drop the unliked patch, introduce a new patch 1 according to mst's comments.
2. base on the new patch, remove the following statements

        /* Any error other than -ENOTSUP(board's MSI support is broken)
         * is a programming error */
        assert(!ret || ret == -ENOTSUP);

   for the affected device: megasas, hcd-xhci. This is trivial changes,
   so I left the R-bs where it was.

Test:
1. Detailed test via command line as v9
2. make check hangs at: GTESTER check-qtest-x86_64. After ctrl-C, it says:

    make: *** [check-qtest-x86_64] Interrupt
    qemu-system-x86_64: Failed to read msg header. Read -1 instead of 12. 
Original request 11.

    qemu-system-x86_64: Failed to set msg fds.

   Is it a regresstion or I missed something?
