[rt2x00-users] [PATCH] rt2x00 : Fix for the index hack in txdone

[Alban Browaeys]

Fix one every 24 entries processed error. Still there are lot of other missed entries that makes
no sense to me yet (only happens for big skb->len though any of the big ones goes through without issue : 367, 423 does not pass while 432 does ... could be a padding/round issue even though I tried a few roundup(skb->len,4) , roundup(skb->len+4,4) trying to reproduce what is in rt2800usb got get_tx_len ... though I have not found the correct register to apply this to - and how to have this padding added while the dma memory allocated is fixed for the pci driver).

For the previous patch I did not managed to inline it properly via  :
git format-patch --signoff --stdout --inline origin | git imap-send
Don't know why it ended up attached. This one too so I copy n'pasted in the email. Hope it does not end up flowed or wrapped even though
I followed the howto to prevent that.
Sorry.

Alban

When index is 0 - 1 it is queue limit.
