5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yanteng Si <siyanteng@xxxxxxxxxxx>
[ Upstream commit c70f3163681381c15686bdd2fe56bf4af9b8aaaa ]
Reference and PTP clocks rate of the Loongson GMAC devices is 125MHz.
(So is in the GNET devices which support is about to be added.) Set
the respective plat_stmmacenet_data field up in accordance with that
so to have the coalesce command and timestamping work correctly.
Fixes: 30bba69d7db4 ("stmmac: pci: Add dwmac support for Loongson")
