USB: asix - Add AX88178 support and many other changes
* More generi-fication of function/macro names where appropriate: ax88772_xx() -> asix_xx() * Reorder functions to provide more logical grouping * AX88178 device support * Support DLink DUB-E100 Rev B Support * Hopefully resolve all endian-ness issues * Use more defines for bitmask values * Change a number of devdbg() calls to deverr() so that if DEBUG is not defined, the error messages still get through as necessary Signed-off-by: David Hollis <dhollis@davehollis.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
