be2net: Fixup profile management routines
1) Parse PCIe descriptor for max-VFs supported by HW 2) Cleanup NIC descriptor parsing in get_func/profile_config() routines 3) Use common struct definitions for v0 and v1 versions of GET_FUNC_CONFIG Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.
