[PATCH 2/3] net: ethernet: ti: cpsw: remove redundant check in napi poll

From: Ivan Khoronzhuk <hidden>
Date: 2016-08-04 21:16:22
Also in: linux-omap, lkml
Subsystem: networking drivers, the rest, ti ethernet switch driver (cpsw) · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

No need to check number of handled packets, when in most cases (> 99%)
it's not 0. It can be 0 only in rarely cases, even in this case
it's not bad to print just 0.
