From: Jie Liu <[email protected]>
The MSIX entry in sxe2_net_map_addr_info_pf sets a register width
of 10 (decimal), but each PCIe MSIX table entry is 16 bytes (0x10).
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.
