Subject: [PATCH] net: ethernet: mtk_eth_soc: fix tx throughput regression with
direct 1G links
Using the QDMA tx scheduler to throttle tx to line speed works fine for
switch ports, but apparently caused a regression on non-switch ports.
Based on a number of tests, it seems that this throttling can be safely
dropped without re-introducing the issues on switch ports that the
tx scheduling changes resolved.
