Commit Message

Ting Xu Sept. 27, 2020, 12:42 p.m. UTC
Add support to negotiate large VF capability, configure VSI queues,
enable/disable queues and IRQ mapping for large VF. Use new virtchnl
opcodes and structures to support max 256 queue pairs. Request
additional queues from PF first if current allocated queues are not
enough. Query max RSS queue region for future RSS configuration.
