Subject: [PATCH net-next 2/2] bnx2x: use the default NAPI weight

From: Eric Dumazet <edumazet@...gle.com>

BQL (Byte Queue Limits) proper operation needs TX completion
being serviced in a timely fashion.

bnx2x uses a non standard NAPI poll weight, and thats not fair to other
napi poll handlers, and even not reasonable.

Use the default value instead.
