This series brings a variety of fixes and enhancements for mtk_eth_soc,
adds support for the MT7981 SoC and facilitates sharing the SGMII PCS
code between mtk_eth_soc and mt7530.

Daniel Golle (9):
  net: ethernet: mtk_eth_soc: add support for MT7981 SoC
  net: ethernet: mtk_eth_soc: set MDIO bus clock frequency
  net: ethernet: mtk_eth_soc: reset PCS state
  net: ethernet: mtk_eth_soc: only write values if needed
  net: ethernet: mtk_eth_soc: fix RX data corruption issue
  net: ethernet: mtk_eth_soc: ppe: add support for flow accounting
  net: pcs: add driver for MediaTek SGMII PCS
  net: ethernet: mtk_eth_soc: switch to external PCS driver
  net: dsa: mt7530: use external PCS driver

Thanks! I've now successfully tested this on an MT7986 board with 2.5G
phys (GPY211C) connected to one of the mtk_eth_soc macs and on port 5 of
the the MT7531.  The series fixes a number of issues for me, including a
mysterious packet drop at 1G only which I believe is related to the
undocumented MAC_MCR_BIT_12 in patch 5.

With Vladimir's (WiP?) "PCS and PHY in-band sync" patch set and your
related implementations in mxl-gpy, mt7530 and mtk_eth_soc to top of
this series, both 2.5G ports are now usable at any speed.

Note that the mt7530.c part of the series depends on 
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git/commit/?id=697c3892d825fb78f42ec8e53bed065dd728db3e
which is not yet in net-next. It appears to be destined for v6.2 so this
is not a problem.  Just mentioning it in case someone else is struggling
with the testing of this series.

Feel free to add

to the complete series.
