MicroSemi Switchtec management interface driver
Microsemi's "Switchtec" line of PCI switch devices is already well supported by the kernel with standard PCI switch drivers. However, the Switchtec device advertises a special management endpoint with a separate PCI function address and class code. This endpoint enables some additional functionality which includes:
* Packet and Byte Counters * Switch Firmware Upgrades * Event and Error logs * Querying port link status * Custom user firmware commands
Add a switchtec kernel module which provides PCI driver that exposes a char device. The char device provides userspace access to this interface through read, write and (optionally) poll calls.
A userspace tool and library which utilizes this interface is available at [1]. This tool takes inspiration (and borrows some code) from nvme-cli [2]. The tool is largely complete at this time but additional features may be added in the future.
