Revision 449cfcc1cd28a1c16321c47b1e7e77138411a72a authored by Michal Schmidt on 23 August 2013, 13:40:53 UTC, committed by David S. Miller on 27 August 2013, 18:59:27 UTC
Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT")
netif_napi_add() produces an error message if a NAPI poll weight
greater than 64 is requested.

jme requests a quarter of the rx ring size as the NAPI weight.
jme's rx ring size is 1 << 9 = 512.

Use the standard NAPI weight.
