Meanwhile what is currently implemented defines 10/100/1000 link speeds for all IP-cores, which is definitely incorrect for DW MAC100, DW XGMAC and DW XLGMAC devices. Seeing the flow-control is implemented as a callback for each MAC IP-core (see dwmac100_flow_ctrl(), dwmac1000_flow_ctrl(), sun8i_dwmac_flow_ctrl(), etc) and since the MAC-specific setup() method is supposed to be called for each available DW MAC-based device, the capabilities initialization can be freely moved to these setup() functions, thus correctly setting up the MAC-capabilities for each IP-core (including the Allwinner Sun8i). A new stmmac_link::caps field was specifically introduced for that so to have all link-specific info preserved in a single structure. Note the suggested change fixes three earlier commits at a time. The commit 5b0d7d7da64b ("net: stmmac: Add the missing speeds that XGMAC supports") permitted the 10-100 link speeds and 1G half-duplex mode for DW XGMAC IP-core even though it doesn't support them. The commit df7699c70c1b ("net: stmmac: Do not cut down 1G modes") incorrectly added the MAC1000 capability to the DW MAC100 IP-core. Similarly to the DW XGMAC the commit 8a880936e902 ("net: stmmac: Add XLGMII support") incorrectly permitted the 10-100 link speeds and 1G half-duplex mode for DW XLGMAC IP-core.
