From: Ivo van Doorn <[email protected]>
Patch:
rt2x00: Make rt2x00_queue_entry_for_each more flexible
commit: 10e11568ca8b8a15f7478f6a4ceebabcbdba1018
introduced a severe regression on the throughput
for USB hardware. It turns out that the exiting of
the rt2x00queue_for_each_entry() was done too early.
The exact cause for this regression is unknown,
but by disabling the premature exiting of the loop
seems to resolve the issue.
