Subject: [PATCH net] net: ethernet: mediatek: Fix bit field in
 mtk_set_queue_speed()

This was supposed to set "FIELD_PREP(MTK_QTX_SCH_MAX_RATE_WEIGHT, 1)"
but there was typo and the | operation was missing and which turned
it into a no-op.

Fixes: f63959c7eec3 ("net: ethernet: mtk_eth_soc: implement multi-queue support for per-port queues")
