- Adds FW logging support
- Once enabled, this lets the firmware print event and error messages
to the log, increasing the visibility into what the hardware is
doing; this is useful for debugging
- General bug fixes
- Adds inital DCB support to the driver
- Notably, this adds support for DCBX to the driver; now with the
fw_lldp sysctl set to 1, the driver and adapter will adopt a DCBX
configuration sent from a link partner
- Adds statistcs sysctls for priority flow control frames
- Adds new configuration sysctls for DCB-related features: (VLAN) user
priority to TC mapping; ETS bandwidth allocation; priority flow
control
- Remove unused SR-IOV files (until support gets added)
