Re: RFR: new SiS gige driver

Comments:
	- Run through lindent, indenting is non-standard.

	- struct board_info defined but only used in one debug message
	  and it is just a string.

	- C99 initializers?

	- if code is commented out and outdated remove it (see init_board)

	- poisoning memory is useless and done already by allocator
	  (see SIS190_remove_one)

	- assert checks for null pointers are overkill

	- ethtool?

Overall, suffers a little from the "having more debug code makes my
driver more reliable" fallacy.
