The VF map table already uses 0x10. Since reg_width is used as the stride between MSIX entries in sxe2_dev_pci_seg_map(), the wrong value makes the mapped region too short and places the entries at incorrect offsets. Change .reg_width from 10 to 0x10 for the SXE2_PCI_MAP_RES_IRQ_MSIX entry to match the VF table.
