   3 Subject: [PATCH] iwlagn: fix warning when set WEP key
   4 Patch-mainline: 2.6.29? (wireless-testing: 31078197aa3ab891b1260627c0497e07060222c8)
   5 References: bnc#487247

   7 iwl_clear_station_table will be called every time rxon called.
   8 In this function ucode_key_table is set to 0 even though a static
   9 WEP security is set. This will cause in many warning and might be
  10 an issue if dynamic WEP is set. This patch make sure we keep track
  11 of all existing static WEP when this function is called.
