iwlwifi: Adjusting PLCP error threshold for 1000 NIC
|
||
|
|
|
||
|
|
While testing the station with the NIC 1000 family, it is found that
|
||
|
|
the plcp error can easily exceed 50 value in 100mSecs. This creates
|
||
|
|
unneccessary radio reset/tuning. This patch raises the PLCP error
|
||
|
|
threshold of the NIC 1000 from 50 to 200 error count.
