MT7981,7986 and 7988 all supports 32768 PPE entries, but only set to 8192 entries in driver. So incrase max entries to 12768 instead. Signed-off-by: Elad Yifee <redacted> Signed-off-by: Shengyu Qu <redacted> --- This patch is set to RFC because I cannot find any documentation for earlier devices like MT7621 that describes their max entries, and need more information or testing to find out whether this patch would work on those devices. --- drivers/net/ethernet/mediatek/mtk_ppe.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
