2022-10-28net: mtk_eth_soc: eliminate unnecessary error handlingRussell King (Oracle)1-12/+6
The functions called by the pcs_config() method always return zero, so there is no point trying to handle an error from these functions. Make these functions void, eliminate the "err" variable and simply return zero from the pcs_config() function itself.

2022-10-28net: mtk_eth_soc: add definitions for PCSRussell King (Oracle)1-3/+10
As a result of help from Frank Wunderlich to investigate and test, we know a bit more about the PCS on the Mediatek platforms. Update the definitions from this investigation. This PCS appears similar, but not identical to the Lynx PCS. Although not included in this patch, but for future reference, the PHY ID registers at offset 4 read as 0x4d544950 'MTIP'.

2022-09-27net: ethernet: mtk_eth_soc: fix usage of foe_entry_sizeDaniel Golle1-1/+1
As sizeof(hwe->data) can now longer be used as the actual size depends on foe_entry_size, in commit 9d8cb4c096ab02 ("net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc") the use of sizeof(hwe->data) is hence replaced. However, replacing it with ppe->eth->soc->foe_entry_size is wrong as foe_entry_size represents the size of the whole descriptor and not just the 'data' field. Fix this by subtracing the size of the only other field in the struct 'ib1', so we actually end up with the correct size to be copied to the data field.

2022-09-20net: dsa: introduce dsa_port_get_master()Vladimir Oltean1-1/+1
There is a desire to support for DSA masters in a LAG. That configuration is intended to work by simply enslaving the master to a bonding/team device. But the physical DSA master (the LAG slave) still has a dev->dsa_ptr, and that cpu_dp still corresponds to the physical CPU port. However, we would like to be able to retrieve the LAG that's the upper of the physical DSA master. In preparation for that, introduce a helper called dsa_port_get_master() that replaces all occurrences of the dp->cpu_dp->master pattern. The distinction between LAG and non-LAG will be made later within the helper itself.

2022-07-18net: ethernet: mtk_eth_soc: fix off by one check of ARRAY_SIZETom Rix1-1/+1
In mtk_wed_tx_ring_setup(.., int idx, ..), idx is used as an index here struct mtk_wed_ring *ring = &dev->tx_ring[idx]; The bounds of idx are checked here BUG_ON(idx > ARRAY_SIZE(dev->tx_ring)); If idx is the size of the array, it will pass this check and overflow. So change the check to >= .
