The intention here is to replace frame types from enum ath5k_pkt_type 
with their AR5210-specific counterparts.  So the intention is definitely 
to have breaks here.

Unfortunately, AR5210 cards are extremely rare these days.  I have one, 
but it only works with old motherboards.  It would take me half a day to 
dust off that system, compile the kernel and check the patch.  But I 
assume your patch is fine.  At least it's very unlikely to break anything.

That is in an #if 0 block. Maybe we should remove the #if 0? Yuan-Hsin?

That is in an #if 0 block. Maybe we should remove the #if 0? Yuan-Hsin?

It's ok to remove the #if 0. But the warning will occur while compling.

By removing the #if 0 block I meant to remove the unused functions
fusb300_cmp_dbg_fifo() and fusb300_dbg_fifo(). There should be no
warning then.
Are you okey with this? Are those function required?

These funtions are used for debugging. I think it's ok to remove them. Thanks.

These functions were used to debug unstable hw fifo while developing fusb300.  It's much more stable now.
So these functions can be removed. Thanks for your advice.
