[PATCH 2.6.39 v2] iwlegacy: led stay solid on when no traffic

[Wey-Yi Guy]

commit 843f26f06a41c5797f19e843c23ca4ed2a71a0bc change the led behavior
for iwlwifi driver; the side effect cause led blink all the time.

Modify the led blink table to fix this problem

Patch seems fine, but I can't find the listed commit ID that caused this issue?

commit 843f26f06a41c5797f19e843c23ca4ed2a71a0bc
Author: Johannes Berg <johannes.berg@intel.com>
Date:   Wed Dec 15 07:30:01 2010 -0800

    iwlwifi: use mac80211 throughput trigger
    
    Instead of keeping track of LED blink speed
    in the driver, use the new mac80211 trigger
    and link it up with an LED classdev that we
    now register. This also allows users more
    flexibility in how they want to have the LED
    blink or not.
