MFC ixgbe commits for 10.2:
- r280182 - Split the driver into independent pf/vf loadables - r280197 - Resolve build issues - r280204 - Fix multiple same-name devclasses - r280228 - Fix i386 LINT build issues / remove unused variable - r280252 - Fix building ixgbe with gcc - r280962 - Make changes to busdma code similar to r257541 - r281772 & r281773 - Remove unused variable - partial r282280 - stats counter update (ix-only) - r282289 - Add X550 support - r282290 - Add X550 makefile updates - r282293 - Add ixgbe_x550.c to conf/files - r282299 - Fix gcc compile (extraneous extern declaration) Finally, add ix_txrx.c to conf/files because it's required for compile in stable/10.
