value='15'>1520 25 30 35 40 space: include ignore mode: unified ssdiff stat only cxgb4: Set VPD size so we can read both VPD structures
Chelsio adapters have two VPD structures stored in the VPD:
- offset 0x000: an abbreviated VPD, and
- offset 0x400: the complete VPD.
After 104daa71b396 ("PCI: Determine actual VPD size on first access"), the
PCI core computes the valid VPD size by parsing the VPD starting at offset
0x0. That size only includes the abbreviated VPD structure, so reads of
the complete VPD at 0x400 fail.
Explicitly set the VPD size with pci_set_vpd_size() so the driver can read
both VPD structures.
[bhelgaas: changelog, split patches, rename to pci_set_vpd_size() and
return int (not ssize_t)]
Fixes: 104daa71b396 ("PCI: Determine actual VPD size on first access")
