2025-05-22wifi: mt76: mt7996: fix invalid NSS setting when TX path differs from NSSPeter Chiu
The maximum TX path and NSS may differ on a band. For example, one variant of the MT7992 has 5 TX paths and 4 NSS on the 5 GHz band. To address this, add orig_antenna_mask to record the maximum NSS and prevent setting an invalid NSS in mt7996_set_antenna().

2025-05-21wifi: mt76: mt7996: add macros for pci device idsShayne Chen
The chipset name (i.e., brand name) used by the driver may cause confusion with the PCI device ID when adding support for new chipsets. | Chipset name | PCI device id | |--------------|----------------| | 7996 | 0x7990, 0x7991 | | 7992 | 0x7992, 0x799a | | 7990 | 0x7993, 0x799b | To prevent confusion, replace the code that directly uses the device ID with macros.
