Hello experts,

 

I'm using LS1028ARDB, and want to support ENETC in my embedded OS, but we do not have its driver to enable its, so my question is can we use legacy INTx to enable ENETC without MSI-X support? In other words, without MSI-X, only use INTx, such as INTA, INTB, does the ENETC can work normally?

pcie@1f0000000 { /* rcie_enetc */ 623 compatible = "pci-host-ecam-generic"; 624 reg = <0x01 0xf0000000 0x0 0x100000>; 625 #address-cells = <3>; 626 #size-cells = <2>; 627 #interrupt-cells = <1>; 628 msi-parent = <&its>;
