From 6633fb83f1faddbfcac09e35edcae96bd0468335 Mon Sep 17 00:00:00 2001 From: Hayes Wang Date: Thu, 19 Aug 2021 11:05:37 +0800 Subject: r8152: fix the maximum number of PLA bp for RTL8153C The maximum PLA bp number of RTL8153C is 16, not 8. That is, the bp 0 ~ 15 are at 0xfc28 ~ 0xfc46, and the bp_en is at 0xfc48. Fixes: 195aae321c82 ("r8152: support new chips") Signed-off-by: Hayes Wang Signed-off-by: David S.
