short subdev in bdx_device_descr causes PHY lookup failure for subsystem IDs > 0x7FFF

[minenko]

I found this problem with Claude. The proposed fixed worked and made my card working again:

Key points:

Hardware: Edimax EN-9320SFP+ (1fc9:4022 / 1432:8103)
Symptom: "PHY init failed" despite correct PCI ID in bdx_dev_tbl
Root cause: short subdev in struct bdx_device_descr (tn40.h) overflows for 0x8103 = 33027 > 32767
Fix: change short vid/pid/subdev to u16 in tn40.h

The diff for this would be:
diff struct bdx_device_descr {

• short vid;
• short pid;
• short subdev;

• u16 vid;
• u16 pid;
• u16 subdev;
  enum PHY_TYPE phy_type;
  char *name;
  };
