Subject: avf: support generic flow

Support generic flow in native avf.

Enable necessary RSS hash function for generic flow. Extend some
structures and functions from for FDIR only to for both RSS and FDIR
flows. Modify virtual channel message to align with ice kernel driver.

Add functions to parse generic flow patterns. The parsing results will
be delivered to the kernel driver and create corresponding flow rules.

Type: feature
