This is a bug.  Valid values of short_gi_rate are 0 and 1 but this sets
it to BIT(5) so it will break odm_RateUp_8188E() which tests for:

	else if ((pRaInfo->SGIEnable) != 1)


Oh I see, I should have been more careful with this type of removals.

I have not looked at this one to see if has a similar issue...  I don't
necessarily want to audit all of these.  I guess I will, but could you
do it first and then I will check?


Sure I'll do.

Thanks,
