[PATCH net-next v3 3/3] net: dsa: microchip: replace unclear KSZ8830 strings

From: vtpieter
Date: Tue Sep 03 2024 - 03:32:53 EST


From: Pieter Van Trappen <pieter.van.trappen@xxxxxxx>

Replace ksz8830 with ksz88x3 for CHIP_ID definition and other
strings. This due to KSZ8830 not being an actual switch but the Chip
ID shared among KSZ8863/8873 switches, impossible to differentiate
from their Chip ID or Revision ID registers.

Now all KSZ*_CHIP_ID macros refer to actual, existing switches which
removes confusion.
