Subject: [PATCH net 2/2] r8152: fix the maximum number of PLA bp for RTL8153C
Date: Thu, 19 Aug 2021 11:05:37 +0800	[thread overview]
Message-ID: <20210819030537.3730-379-nic_swsd@realtek.com> (raw)
In-Reply-To: <20210819030537.3730-377-nic_swsd@realtek.com>

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")
