[PATCH] ath9k: decrease size of ath9k.ko

[tom.leiming]

From: Ming Lei <tom.leiming@gmail.com>

The patch defines the fields of 'valid_single_stream' and 'valid' in
struct ath_rate_table as char type, so decrease the size of ath9k.ko
about 2KB.

Why 'char' rather than 'u8'? To me, the latter implies a small integer, not
character data.

Either 'char' or 'u8' is OK, since both has one-byte size, isn't it?

Besides Johannes' comment: char is signed, u8 is unsigned. This can sometimes 
byte you.

This version takes Larry's suggestion to define 'valid_single_stream'
and 'valid' as u8 instead of char.

You can use bool instead, and that would give the same size saving while
being even more descriptive.  I think using bool could be safer, as the
compiler would be able to detect some misuses and the values.

But I could get even more saving by using bool with the field width:

bool valid:1;
bool valid_single_stream:1;

That would place both variables into one byte.  It may be ineffective
for speed, but it's more effective for storage.

In my configuration, I get following sizes:

original (int):    2792138
your patch (u8):   2790186
bool:              2790186
bool (1 bit):      2789218

Or use flags, and use BIT(1), BIT(2), etc for #defines for each stream mode.
Would save even more.

Or use flags, and use BIT(1), BIT(2), etc for #defines for each stream mode.
Would save even more.

1bit is not enough, at least 3bit is required for each one.

We does not save more using bit field since size of the least type
is 1 byte.
