   4 Subject: [PATCH] EDMA: Use NAPI_POLL_WEIGHT as NAPI weight
   5
   6 Currently a weight of 100 is used by the EDMA, according
   7 to upstream max of 64 should be used and that is used for
   8 almost any driver.
   9
  10 They also introduced NAPI_POLL_WEIGHT define which equals
  11 to 64.
  12
  13 So use NAPI_POLL_WEIGHT as the weight.
