net: stmmac: update pci platform data to use phy_interface

2020-02-07T10:36:22+00:00

The recent patch to support passive mode converter did not take care the phy interface configuration in PCI platform data. Hence, converting all the PCI platform data from plat->interface to plat->phy_interface as the default mode is meant for PHY.

2020-02-07T10:36:22+00:00

Without checking for IFF_MULTICAST flag, it is wrong to assume multicast filtering is always enabled. By checking against IFF_MULTICAST, now the driver behaves correctly when the multicast support is toggled by below command:- ip link set multicast off|on Fixes: 0efedbf11f07a ("net: stmmac: xgmac: Fix XGMAC selftests") Signed-off-by: Tan, Tee Min Signed-off-by: Ong Boon Leong Signed-off-by: David S.

net: stmmac: xgmac: fix incorrect XGMAC_VLAN_TAG register writting

2020-02-07T10:36:21+00:00

snps databook noted that physical coding sublayer (PCS) interface that can be used when the MAC is configured for the TBI, RTBI, or SGMII PHY interface. we have RGMII and SGMII in a SoC and it also has the PCS block. it needs stmmac_init_phy and stmmac_mdio_register function for initializing phy when it used RGMII interface.
