sis190: fix gigabit negotiation
Fixes an initialization error; the chip negotiates gigabit, but the driver mistakenly handled it as 100Mb. Changes based on both SiS own GPL driver and forcedeth. Hopefully should fix http://bugzilla.kernel.org/show_bug.cgi?id=9735 http://bugzilla.kernel.org/show_bug.cgi?id=11149 Signed-off-by: Riccardo Ghetta <birrachiara@tin.it> Signed-off-by: David S.
