This device is an ethernet switch core from Microsemi (VSC9959) integrated as PCIe endpoint into the LS1028a SoC.
Though this switch core has some particularities (i.e. 6 ports, some register mapping differences), functionally this driver relies entirely on the Ocelot switch driver providing all the features, and is basically an instance of the Ocelot core driver. The first 3 patches are minor refactoring of the common Ocelot code (core driver). The rest provide the integration code of the switch as a PCIe device, the register mapping, corresponding ls1028a DT nodes (for switch ports link configuration). There are also few particularities described by individual patch messages.
