6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiner Kallweit <hkallweit1@xxxxxxxxx>
[ Upstream commit ced8e8b8f40accfcce4a2bbd8b150aa76d5eff9a ]
RTL8125 added fields to the tally counter, what may result in the chip
dma'ing these new fields to unallocated memory. Therefore make sure
that the allocated memory area is big enough to hold all of the
tally counter values, even if we use only parts of it.
Fixes: f1bce4ad2f1c ("r8169: add support for RTL8125")
